A German town built a granary atop its Jewish cemetery. Now the bones are yielding insights about Ashkenazi DNA.
BERLIN (JTA) – The city of Erfurt in central Germany is home to an impeccably restored medieval synagogue made possible because local Jews had been expelled long before the Nazis began their campaign to destroy Jewish sites.
Now, Erfurt’s long-hidden Jewish past is again offering new insights — this time about the genetic history of Ashkenazi Jews.
Human remains from a medieval Jewish cemetery in Erfurt have allowed what researchers say is the largest ancient Jewish DNA study to date. Conducted without disinterring any remains, in keeping with Jewish law, the study published Wednesday in the scientific journal Cell found that Erfurt’s medieval Jewish community was more genetically diverse than their modern-day cousins, and carried many of the same Jewish genetic diseases — such as Tay Sachs and cystic fibrosis — that affect Ashkenazi Jews today.
“There have been many previous DNA studies, but not of Jews,” said geneticist Shai Carmi, a professor at the Hebrew University of Jerusalem, whose search for study material led him to an archaeological dig at the Jewish cemetery in Erfurt. He and his collaborators were able to analyze DNA of 33 individuals who died between 1270 and 1400, using teeth they found there.
The study follows a similar analysis revealed in August by researchers in England, who studied the DNA from skeletons found at the bottom of a medieval well and concluded that the remains were likely of victims of an antisemitic massacre in 1190. Analysis of six individuals prior to their identification as Jewish revealed that Ashkenazi Jews developed a unique genetic variation centuries earlier than realized.
The Erfurt analysis also includes samples from before the epidemic of Black Death that was until recently understood to have created the genetic “bottleneck” that created the genetic markers common among Ashkenazi Jews today.
Erfurt’s Jewish settlement existed from the 11th to 15th century, with a brief gap following a 1349 massacre perpetrated after the Jews were falsely blamed for causing the bubonic plague. Surviving Jews returned there, but after all Jews were expelled once and for all in 1454, the city built a granary on top of the Jewish cemetery.

In 2013, the city approved the repurposing of the unused granary into a parking lot. Because it was an historic site, a rescue excavation was initiated, overseen for the State of Thuringia by German archaeologist Karin Sczech.
Meanwhile, Carmi had been looking for Jewish cemeteries anywhere in the world “where we could analyze remains already excavated,” he told JTA in a telephone interview from Jerusalem. “I consulted historians and eventually reached the archeologist in Erfurt.” Fortunately, he said, “they still hadn’t reburied the remains.”
He approached Sczech, who later became a co-author of the new study. In 2018, with a supportive judgment from Rabbi Ze’ev Litke — an Israeli expert on genetics and Jewish law — and permission from Erfurt’s then-rabbi, Benjamin Kochan, work began to extract and analyze DNA from detached teeth found in the graves. (About 500 Jews live in Erfurt today, most of them having migrated from the former Soviet Union since 1990.)
American geneticist David Reich picked up the teeth and brought them back to the department of human evolutionary biology at Harvard University in Cambridge, Massachusetts, where drilling and DNA extraction took place.
While the skeletons were reburied, the teeth are still stored at the research institutes where they have been analyzed, in case scientists need to retest to verify the result.
The project provides an ethical basis for studies of ancient Jewish DNA, Carmi said. “Of course we couldn’t just go to a cemetery and dig and take out skeletons; this would be prohibited,” he said, referring to Jewish law prohibiting the removal of bones from where someone was buried.
But Litke opined that the study could be done, because the bones already had been disturbed for an unrelated reason. “He recommended using teeth, as the analysis does almost no damage,” Carmi said.
There are many motivations to study Jewish DNA: One can find lost relatives going back a few generations, and answer questions about Jewish origin of partners intending to marry. But the goal of Carmi’s team was “to fill the gaps in our understanding of Ashkenazi Jewish early history.”
There are several non-destructive ways to obtain DNA from human remains, said Carmi, who also works as a consultant to an Israeli firm that helps clients trace their genetic roots.
“You can take an almost microscopic slice of bone and extract DNA in a solution, or put the entire bone in a solution and extract the DNA without drilling, without disturbing the dead. This opens the way to doing studies even without teeth,” he added.
His team found that the Erfurt community appeared to fit into two genetically distinct groups, descending either from Middle Eastern or European populations. This genetic variability no longer exists, Carmi said.
At the same time, Carmi said, the analysis found remarkable continuity in the local community, as well. “One third of the Erfurt individuals descended from one woman through their maternal lines,” he said, adding that evidence suggested that she lived between 1,000 and 2,000 years ago.
In a press statement, geneticist Reich of Harvard said the work “also provides a template for how a co-analysis of modern and ancient DNA data can shed light on the past. Studies like this hold great promise not only for understanding Jewish history, but also that of any population.”
The research team, with more than 30 scientists, included Hebrew University’s Shamam Waldman, a doctoral student in Carmi’s group, who performed most of the data analysis.

Purim gets creative in Israel, with festivities driven underground
TEL AVIV, Israel — On the corner of a sun-bleached side street in Tel Aviv’s Shuk Levinsky, costumed mannequins stand guard over a half-dark shop, their painted eyes fixed on a street gone strangely still. Cardboard boxes of sequined capes and feathered wings spill onto the sidewalk, untouched. The neighboring businesses are shuttered, heavy padlocks fastened across their metal doors.
On any weekday, the quiet would feel unusual in this bustling pocket of south Tel Aviv. But this is Purim week — normally the market’s most frenetic stretch of the year. In ordinary times, the sidewalks would be clogged with parents and teenagers clamoring for last-minute costume details, with vendors shouting prices over the din.
That was precisely the scene just 48 hours earlier, on the Friday before the Purim madness was set to begin. Despite weeks of speculation about a looming confrontation with Iran, most Israelis pressed ahead with their plans. Hamentaschen were baked, school carnivals assembled, parties confirmed. A meme circulated in school group chats: “Can someone let us know if we are supposed to be buying costumes or canned goods?”
Early Saturday morning, an answer came via the piercing trill of the emergency alert system. The United States and Israel had begun what officials described as “preemptive strikes” against Iran. Within hours, thousands of reservists were called up. Citizens scrambled for shelter plans. WhatsApp groups filled with instructions and anxieties. And as Iran launched retaliatory rockets, Israelis absorbed a different blow: Purim was officially canceled.
Hence, the shuk’s current ghost town atmosphere. Inside the darkened shop, Rotem Avidan sat at the register, scrolling on his phone.
“There’s no real reason to be open,” he said. “Mostly I was just bored at home. I’ll probably close up in a couple of hours.”
Avidan has been selling costumes in the shuk for more than 15 years and relies heavily on Purim sales. The day before the holiday is typically his busiest of the year. Instead, he estimates he’ll make about 80% of his usual income.
“It’s not terrible,” he said with a shrug. “But it’s just one more irregular year. We had corona. We had two years of war. This was supposed to be the year things finally went back to normal.”
The past two Purims were indeed subdued, shadowed by the war in Gaza and the fight to bring hostages home. Even celebrations that went ahead felt muted. With the last living hostages returned in October, many had hoped this would finally be an uncomplicated holiday.
To fully grasp why the cancellation hit so hard, one must understand Purim in Israel. This is not a single-event celebration. It is a multi-day spectacle that spills from nursery school classrooms into city streets. Municipal adloyadas — elaborate parades with floats and marching bands — draw families by the thousands. Teenagers roam in coordinated group costumes. It is not uncommon to find yourself seated on a bus beside an elderly woman in full clown makeup, or handed paperwork at the bank by a teller wearing butterfly wings.
None of which would be happening this year.
Children feel the loss most acutely. For many, Purim is the highlight of the school calendar: themed dress-up days, costume parades, parent-run carnivals, and the exchange of mishloach manot before a three-day vacation. On Sunday morning, children across the country woke to the bad news.
Teachers scrambled to salvage what they could. Virtual parades were arranged over Zoom. Students were asked to send photos in costume. Mishloach manot became neighborhood drop-offs.
In some cases, the children made their own Purim joy. In one Tel Aviv apartment building, the kids organized a costume party, complete with printed invitations for guests. Playgrounds around the country — at least those equipped with shelters — were filled with rambunctious children dressed as superheroes and princesses, their bleary-eyed parents dragging slightly behind them.
If children are Purim’s most visible protagonists, they are hardly its only devotees. For young adults, the holiday is the high point of Israel’s nightlife calendar — a sanctioned blur of themed raves and packed bars. This year, the bomb shelter became a stand-in for the nightclub.
Within hours of the first rocket fire, twentysomethings in Tel Aviv’s Florentin neighborhood had organized an impromptu party in a public shelter, complete with makeshift costumes and an amateur DJ. When video of the event went viral, social media flooded with young people asking about the nearest mesibat miklat — a “shelter party.”
Not everyone approved.
“Wow. How disconnected can you be?” one commenter wrote. “People have been killed and you can’t give up your Purim party for one year?”
By nightfall, hundreds had gathered — some in small, shared building shelters for private parties, others in larger municipal bunkers — determined to carve out a pocket of joy, even as Iranian missiles soared overhead.
Shahar Rubin, 24, hadn’t planned on going to a party when he and his friends noticed a stream of people heading into the Dizengoff Center parking garage. “We figured, why not?” he said.
Four stories underground, in one of the city’s largest public shelters, a DJ blasted music as costumed revelers danced beneath the fluorescent lights and exposed concrete.
“This is exactly why we come to Tel Aviv,” said Rubin, who is originally from the north. “There’s nothing like the Purim atmosphere here.”
After more than 400 days of wartime reserve duty in the Israel Defense Forces, the celebration felt like a rare exhale — and perhaps a brief one, before he is called up again. “It was a last hurrah of sorts,” he added, as he and his friends headed off in search of their next mesibat miklat.
Beyond the costumes and parties, Purim is anchored in four religious obligations: a festive meal, the exchange of food gifts, donations to the poor and — most famously — the public reading of Megillat Esther.
“According to Jewish law, men and women are required to hear the reading of the entire Megillah from a kosher scroll,” said Rabbi Nadav Berger, head of Hadar’s Beit Midrash in Jerusalem. “Because the obligation is about publicizing the miracle of Purim, there is a strong preference to do it in public, in a group of at least ten people.”
That preference became complicated as soon as Home Front Command restricted public gatherings.
By the time Shabbat ended, observant Jews were organizing small readings in private homes and shelters. Hadar put out a call for community members who owned kosher megillot.
“Owning a personal megillah isn’t as rare as owning a Torah scroll,” Berger explained. “Many people inherit one or receive one for a bar mitzvah or wedding. Hearing the Megillah in person is still our first recommendation, so we wanted to help facilitate that safely.”
For those unable to attend, Hadar is also offering Zoom options, drawing on halachic guidance developed during the pandemic. “The rulings get into the technical question of how to understand electronically transmitted sound,” Berger said. “But it goes without saying: no one is required to risk their life to hear the Megillah — or to fulfill any other Torah commandment. Safety overrides everything.”
He added: “Typically, one would perform a mitzvah all in one sequence, from beginning to end. But if a siren goes off while you are reading the megillah, it is perfectly acceptable to pause the reading, even for a few hours, until it is safe to return.”
For Berger, the tension between caution and celebration may be truer to Purim than one might expect for a holiday typically associated with pure, unadulterated joy. When he sent out Hadar’s revised Purim plans, he opened with Mordechai’s words to Esther: “Who knows. Perhaps it was for just such a moment that you attained royalty?”
“Meaning, you have to be responsible right now,” Berger explained. “You have to think about your situation and respond accordingly. That’s what we’re trying to do in light of all that’s happening.”
He went on, “If you read the Megillah, most of it is actually anxiety-provoking. It is a very tense story. The joy comes only at the end.”
“The hope,” he said, “is that this, too, is only the middle — and that Israel will once again return to celebrating Purim happily, joyously, as we do every year.”

Fears of Iranian Sleeper Cell Retaliation Grow in the West as Middle East War Escalates

Fears of Iranian-backed terrorism are intensifying across Western countries, with officials warning Iran could mobilize terrorist sleeper cells and proxy networks in revenge for the unprecedented US-Israeli strikes on Saturday that killed Supreme Leader Ayatollah Ali Khamenei — prompting governments to raise threat levels and bolster security for Jewish and Israeli communities abroad.
Sleeper cells are covert operatives or terrorists embedded in rival countries who remain dormant until they receive orders to act and carry out attacks.
As the war in the Middle East continues to spread and escalate, officials in Germany have warned of potential Iranian retaliation targeting Jewish and Israeli institutions nationwide, prompting several federal states to step up protections and issue alerts as threat concerns mount.
“Retaliatory measures — including the possible activation of Iranian sleeper cells in Europe — cannot be ruled out,” Marc Henrichmann, who chairs the parliamentary oversight committee of the intelligence services in Germany, told the local newspaper Süddeutsche Zeitung.
“The Iranian regime has repeatedly shown that it extends its use of terror beyond its own borders,” Henrichmann said. “Federal and state security authorities remain on the highest alert level and will adjust protective measures whenever necessary.”
Roman Poseck, the interior minister of the German state of Hesse, added to German outlet Die Welt that it should “be assumed that there will be an increase in the abstract threat situation, especially for Jewish, Israeli, and American institutions.”
Meanwhile, Felix Klein, the German government’s commissioner for combating antisemitism, warned to the Funke media group that, following the outbreak of conflict with Iran, “we must assume an increased threat to Jewish life in Germany.”
In France, Interior Minister Laurent Nuñez also issued a heightened alert, warning of potential threats and urging regional authorities to reinforce security around Jewish places of worship.
“In light of the current international situation in the Middle East, I reiterate my instructions to remain vigilant and ask you to immediately implement enhanced security measures for Jewish places of worship and religious gatherings,” Nuñez told French newspaper Le Figaro.
The United States and Israel carried out a series of strikes on military and leadership targets across Iran — including senior officials and Islamic Revolutionary Guard Corps commanders — after negotiations over Tehran’s nuclear and missile programs failed to yield results.
Shortly after reports emerged that the US–Israeli joint operation may have killed Khamenei, US President Donald Trump released a message urging Iranians to consider a future beyond the current regime and expressing guarded hope that the moment could lead to meaningful change.
The escalation came weeks after the Iranian regime killed tens of thousands of civilians in a sweeping crackdown on last month’s anti-government protests. The outbreak of fighting also followed last June’s 12-day war between Iran and Israel, which concluded after the US joined and bombed Iranian nuclear sites.
Beyond Europe, fears of Iranian retaliation are rising in the US, as counterterrorism agencies warn that additional resources are being rushed into efforts to detect and disrupt potential revenge attacks on American soil.
Although no specific credible threats have been publicly disclosed, FBI Director Kash Patel said Saturday that US counterterrorism and intelligence agencies were operating under heightened alert, with personnel “working 24/7 … to address and disrupt any potential threats” on US soil.
“While the military handles force protection overseas, the FBI remains at the forefront of deterring attacks here at home – and will continue to have our team work around the clock to protect Americans,” Patel wrote in a post on X.
Amid growing fears of possible retaliation, Secretary of Homeland Security Kristi Noem also said authorities are “in direct coordination with our federal intelligence and law enforcement partners as we continue to closely monitor and thwart any potential threats to the homeland.”
Concerns over the activation of Iran’s sleeper cells have surged even further after a deadly mass shooting in Austin, Texas involving a suspect with alleged support for the Islamist regime and a separate gun attack on the gym of an Iranian dissident in Richmond Hill, Ontario. Both incidents stoked fears of politically motivated violence linked to the broader regional crisis in the Middle East.
On Sunday, a gunman opened fire at a bar in Austin’s West Sixth Street district, killing two people and injuring 14 others before being shot and killed by police.
Authorities later reported finding a flag of the Islamic Republic and photographs of Iranian leaders inside the suspect’s apartment, deepening concerns about potential links between the attack and broader political or ideological influences.
According to the FBI and the Joint Terrorism Task Force, there were indicators that could suggest a possible terrorism link.
In Canada, hours after the announced death of Khamenei, a boxing gym run by Iranian-Canadian dissident activist Salar Gholami was struck by gunfire overnight.
Tehran’s ability to coordinate or inspire attacks on American soil has long been a concern for US law enforcement and intelligence officials — a fear that only deepened after Trump ordered the assassination of Iranian General Qasem Soleimani in 2020.
Amid the 12-day war in June, NBC News reported that Iran had privately warned the United States that it could activate sleeper cells on American soil in response to military action. While no specific plots were publicly disclosed, US authorities increased domestic security measures and intelligence monitoring in anticipation of possible attacks. Vice President JD Vance said the Trump administration was examining the possibility of an Iran-backed homeland attack “very closely.”

‘Death to America’: Campus Student Groups Express Solidarity With Iran, Call for Uprising Against US

Anti-Zionist student groups across the US proclaimed solidarity with the aims of Islamism and jihad following a joint military operation between the US and Israel which killed Iranian Supreme Leader Ayatollah Ali Khamenei and dozens of other high-level regime officials on Saturday.
“Death to America,” posted a group which calls itself Columbia University Apartheid Divest (CUAD), a Students for Justice in Palestine (SJP) spinoff which serves as an umbrella group for a consortium of revolutionary organizations, some of which are formally recognized by the university. “We yearn for the end of the US settler colonial project. This should not be a controversial position.”
In other posts, the group shared an April 24 tweet in which Khamenei told pro-Hamas college students, who were in the middle of convulsing higher education institutions with illegal building occupations and antisemitic hate crimes, that they are “on the right side of history” and another which said “Iran has every right to defend itself against zionist [sic] warfare.”
A torrent of criticism followed the comments, leading Columbia University to denounce CUAD for falsely claiming to be a university entity.
“The group that calls itself ‘CUAD’ is not a recognized student group, or affiliated in any way with the university,” the institution said on the X social media platform, pointing to a July 2025 statement by former interim president Claire Shipman which formally proscribed any official correspondence or communication with CUAD. “There is no evidence that anyone currently in control of their account is a current Columbia student, staff, or faculty member. They are illegally using the Columbia name.”
Dr. Asaf Romirowsky, executive director of Scholars for Peace in the Middle East, said American officials should take CUAD’s rhetoric seriously.
“Cheering on Hamas and supporting Iran, a state sponsor of terrorism that has scores of American blood on their hands, surely warrants consequences,” he said. “We already have a great and sensible law on the books which says that while we welcome anyone who wishes to come here, attend university, and get an education, we do not permit people who openly support and advocate for terrorism. Actively supporting terrorism while calling for death to America and chanting ditties that advocate the annihilation of the world’s sole Jewish state should be a red line that warrants expulsion and deportation for those on student visas.”
CUAD is not the only group which denounced what the US dubbed “Operation Epic Fury.” On Sunday, New York University’s SJP chapter announced an anti-US demonstration to “demand an end to this criminal war that benefits no one other than US corporate interests.”
Meanwhile, DMVSJP, a network of SJP groups operating in Washington DC, Maryland, and Virginia, implored socialists and other revolutionary groups to attend a demonstration outside the White House on Monday, charging that “another US-backed war would mean death and displacement abroad and repression at home.”
The University of Chicago’s SJP chapter cheered Iran’s retaliatory strikes against US assets in Bahrain.
Some protests have kicked off already, according to social media reports, and have seen members of Yale’s SJP chapter brandishing “Death to America” signs. Prior to the demonstration, the group parroted propaganda confected by what remained of Iran’s political leadership following this weekend’s strikes, accusing the US of “killing children, including civilians.”
In the United Kingdom, the Ahlul-Bayt Islamic Society of University College London said, “This is not the end to resistance. The Shia in the west [sic] must remain aware and ready.”
Writing to The Algemeiner on Sunday, Sabrina Soffer, research fellow at the Jerusalem Center for Security and Foreign Affairs, said SJP’s statements are indicative of an ideology which contradicts itself.
“Even after the death of one of the Middle East’s most brutal butchers, they cannot offer even a scintilla of credit to Israel or the United States for confronting a regime that has terrorized its own people for decades,” Soffer said. “They brand themselves ‘anti-war’ yet refuse to recognize that the only genuinely anti-war force in this equation is the one dismantling the infrastructure of terror and repression. Israeli and American actions aimed at weakening a violent theocracy are not acts of aggression against the Iranian people — they are part of a rescue operation on behalf of a population held hostage by its rulers.”
She added, “What is truly un-progressive is the arrogance of presuming to speak for Iranians while ignoring those who have risked imprisonment and death resisting the regime from within. It is entitlement masquerading as solidarity.”
Students for Justice in Palestine’s national office has previously discussed its strategy of using the anti-Zionist student movement as a weapon for destroying the US in a now-deleted tweet that was posted to X in September 2024.
“Divestment is not an incrementalist goal. True divestment necessitates nothing short of the total collapse of the university structure and American empire itself,” the organization said. “It is not possible for imperial spoils to remain so heavily concentrated in the metropole and its high-cultural repositories without the continuous suppression of populations that resist the empire’s expansion; to divest from this is to undermine and eradicate America as we know it.”
The tweet was at the time the latest in a series of progressive revelations of SJP’s revolutionary goals and its apparent plans to amass armies of students and young people for a long campaign of subversion against US institutions, including the economy, military, and higher education. Like past anti-American movements, SJP has also been fixated on the presence and prominence of Jews in American life and the US’s alliance with Israel, the world’s only Jewish state.
On the same day the tweet was posted, CUAD distributed literature calling on students to enlist in a holy war against Israel and the US.
“This booklet is part of a coordinated and intentional effort to uphold the principles of the thawabit and the Palestinian resistance movement overall by transmitting the words of the resistance directly,” it said. “This material aims to build popular support for the Palestinian war of national liberation, a war which is waged through armed struggle.”
Other sections of the literature were explicitly Islamist, invoking the name of “Allah, the most gracious” and referring to Hamas as the “Islamic Resistance Movement.” Proclaiming, “Glory to Gaza that gave hope to the oppressed, that humiliated the ‘invincible’ Zionist army,” it said its purpose was to build an army of Muslims worldwide.
“We call upon the masses of our Arab and Islamic nations, its scholars, men, institutions, and active forces to come out in roaring crowds tomorrow,” it added, referring to an event which took place in December. “We also renew our invitation to the free people and those with living consciences around the world to continue and escalate their global public movement, rejecting the occupation’s crimes, in solidarity with our people and their just cause and legitimate struggle.”
