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.

Iran Urges Citizens to Spy on One Another as US-Israeli Strikes Cripple Regime

Amid relentless US and Israeli airstrikes that have decimated Iran’s military capabilities and key energy facilities, Iran has called on citizens to report on each other in a new push to crush domestic dissent, as talks of a possible ceasefire remain uncertain.
On Thursday, the semi-official Fars News Agency, which is affiliated with Iran’s Islamic Revolutionary Guard Corps (IRGC), called on all Iranian citizens to help “identify those who have turned their backs on the homeland and threaten national security,” warning that “the country is facing external threats and internal betrayals.”
“Iranians will not allow this betrayal to be forgotten,” Fars wrote in a post on X, linking to a website called “Our Memory” to offer a platform for citizens to snoop and inform on each other.
“The efforts of ‘Our Memory’ also carry a clear message to those who might be contemplating betrayal or collaboration with the country’s enemies: The society is vigilant and awake, and actions that pose a threat to national security will be identified and exposed,” Fars posted.
The regime’s latest propaganda campaign of intimidation comes as Israel’s offensive increasingly focuses on dismantling Iran’s internal repression systems, aiming to create a leadership vacuum and logistical breakdown that could hinder Tehran’s ability to respond if mass protests erupt again.
Even amid Israel’s major battlefield advances, however, a senior Israeli security official said Wednesday that Iran still retains the ability to launch missiles at its current rate for the next several weeks, according to Israel’s N12 media outlet.
“Iran can maintain its current rate of missile fire for weeks,” the Israeli official reportedly said in a closed-door briefing. “It has sufficient launchers and reinforced squads to sustain and stagger the attacks over time.”
On Thursday, US President Donald Trump announced he was extending, “at the request of the Iranian government,” the deadline to strike the country’s energy grid by 10 days, as Washington works to bring a possible ceasefire deal to the table.
Should diplomatic efforts falter, the Pentagon and US Central Command are reportedly preparing military plans for a “finishing blow” on Iran, potentially involving some level of ground forces and massive airstrikes.
According to multiple media reports, Washington is considering several options against Iran, including invading or blockading Kharg Island, the country’s main oil export hub, or even seizing Arak Island to secure control over the Strait of Hormuz, a critical passage through which roughly a fifth of the world’s oil supply flows.
Other potential measures include taking Abu Musa and two close islands near the western entrance of the strait or blockading or seizing ships exporting Iranian oil on the eastern side, threatening a vital route for global energy shipments.
Since the start of the war last month, combined US and Israeli strikes have dropped more than 25,000 munitions on targets in Iran, with nearly 15,000 of those carried out by the Israeli Air Force alone, according to updated Israeli intelligence data.
“These numbers are large and significant by any measure,” a senior Israeli military officer told the Hebrew-language news site Walla.
“We are concentrating strikes on the regime’s centers of gravity in Tehran, Isfahan, and other key sites. Iran may be a large country, but hitting the very heart of its infrastructure has a profound strategic impact,” he continued.
He also said the operation, which began with “leadership decapitation” and quickly shifted to paralyzing surface-to-surface and surface-to-air missile arrays, has effectively reduced Iran’s missile firing to low single- or double-digit daily levels, far below its plan of over 100 launches per day.
So far, Israel has destroyed more than 200 launchers, even as mobile units hidden in deep tunnels continue to pose serious obstacles, which are being bombed and blocked since missiles cannot always reach their depths.
Israeli forces have also systematically targeted Iran’s weapons manufacturing, attacking over 1,000 sites to degrade production, development, and research capabilities.
According to a Reuters report, US intelligence can only confirm the destruction of about a third of Iran’s missile arsenal, while another third has likely been damaged, destroyed, or buried in underground bunkers, with a similar situation affecting the regime’s drone capabilities.
While most of Iran’s missiles have been destroyed or rendered inaccessible, Tehran still may retain a significant stockpile and, as of now, could potentially recover some buried or damaged missiles after the current fighting ends.
As the war continues to escalate, Israel has shifted its strategy, with its Air Force last week striking a major natural gas processing facility in southwestern Iran — a move that damaged roughly 40 percent of the country’s gas production capacity.
Facing a gas shortage, the Iranian government was reportedly forced to prioritize fuel for electricity production, sharply cutting civilian fuel allocations and causing major disruptions to transportation and deliveries to Turkey.
“This is just a sample of our ability to crush Iran’s energy backbone,” an Israeli security official told N12.
With the US also threatening strikes on key Iranian energy infrastructure, the Islamist regime is now facing pressure to consider a ceasefire agreement to bring the war to a close.
“The Iranians are in panic,” the Israeli official said. “They understand that further damage [to its energy facilities] will make governing the country impossible.”
In one of the latest blows to the regime, the Israeli Air Force on Friday attacked the heavy water reactor in Arak, central Iran, after Israeli intelligence detected repeated attempts to restore the site — a facility considered key for producing plutonium for nuclear weapons.
Israeli officials also confirmed an attack on Iran’s only facility in Yazd that processes raw materials into starting components for uranium enrichment, as well as multiple steel plants in a major blow to an already devastated Iranain economy.
After these attacks, the IRGC threatened to target six steel plants in retaliation, including sites in Israel, Saudi Arabia, the UAE, Bahrain, Qatar, and Kuwait.

Man arrested over alleged firebomb plot targeting pro-Palestinian activist Nerdeen Kiswani
(JTA) — A New Jersey man was arrested on Thursday for allegedly plotting to firebomb the home of the prominent pro-Palestinian activist Nerdeen Kiswani.
Alexander Heifler, 26, was arrested by authorities in Hoboken after a weeks-long undercover operation led by the New York City Police Department revealed that he allegedly planned to throw a dozen Molotov cocktails at Kiswani’s residence.
The investigation into Heifler began in early February when Heifler discussed using Molotov cocktails on a group video call that included an undercover law enforcement officer, according to a criminal complaint filed in the U.S. District Court of New Jersey.
He later told the undercover officer that he had planned to flee the country following the attack. (The criminal complaint did not specify the name of the group or the country he planned to flee to.)
During a search of Heifler’s home Thursday night, detectives and FBI agents uncovered eight Molotov cocktails. He has been charged with unlawful possession of firearms and making of destructive devices.
In a statement Friday, New York City Mayor Zohran Mamdani said that Heifler was an alleged member of the Jewish Defense League, a far-right pro-Israel group that the has FBI labeled as a terrorist organization since 2001, and that the country he had planned to flee to was Israel.
“Last night, an alleged member of the Jewish Defense League — designated by the FBI as a ‘known violent extremist organization’ — attempted to blow up the home of Nerdeen Kiswani in a chilling act of political violence and an apparent assassination plot,” the statement read. “The defendant allegedly planned to flee to Israel following the attack. This comes amidst an alarming rise in threats and violence across the country targeting Palestinian human rights advocates.”
“Let me be clear: We will not tolerate violent extremism in our city. No one should face violence for their political beliefs or their advocacy. I am relieved that Nerdeen is safe,” the statement continued.
A police official confirmed that Heifler was a member of a branch of the Jewish Defense League on Friday, according to The New York Times.
Last month, Kiswani, who has long drawn accusations of antisemitism for her rhetoric on Zionists, sued Betar USA, a far-right militant pro-Israel group, accusing the group of violating her civil rights by putting out social media “bounties” on her and repeatedly harassing her. (In January, Betar USA agreed to dissolve its New York operations following a settlement with the state attorney general.)
The activist has also been singled out by far-right Florida Jewish Rep. Randy Fine, who reposted a tweet of Kiswani’s last month to make disparaging remarks about Muslims which sparked calls for his censure.
In a post on X, Kiswani, a Palestinian-American who co-founded the hardline pro-Palestinian group Within Our Lifetime, wrote that she had been informed by the FBI Joint Terrorism Task Force on Thursday night that “a plot against my life that was ‘about to’ take place.”
“For months, Zionist organizations like Betar and politicians like Randy Fine have encouraged violence against my family and me,” Kiswani continued. “I will have more to say as additional details come to light. I will not stop speaking up for the people of Palestine. Thank you for your support.”
In response to The New York Times’ post about the arrest, Betar USA wrote that it was “not surprising if other terrorists targeted her.”
“Violent terrorist Nerdeen Kiswani wants to globalize the intifada not surprising if other terrorists targeted her. Palestinians have always targeted one another,” the group posted on X alongside a video of Kiswani’s rhetoric. “Not surprising given the violent nature of these people who have globalized the intifada.”
The announcement of the arrest drew praise from the Jewish Community Relations Council of New York, which wrote in a post on X that there is “absolutely no place in our city for violence, threats, or attempts to take someone’s life—ever.”
“While we adamantly disagree with Nerdeen Kiswani’s inflammatory rhetoric and her organization’s tactics, we condemn in the strongest possible terms the reported plot against her,” the group said.
Brad Hoylman Sigal, the Jewish Manhattan borough president, also praised the NYPD for the arrest in a post on X.
“Grateful to @NYPDnews for their swift work in preventing this horrific plot against Nerdeen Kiswani,” Sigal wrote. “Political violence, against anyone, for any reason, has no place in our city.”

The moral degradation of Israel’s far-right is even worse than you think
This week, an Israeli Knesset member said something that should have been shocking, horrifying and unanimously condemned.
“I stand behind IDF soldiers in every situation,” said Yitzhak Kroizer, a member of the ultranationalist Otzmah Yehudit Party. Even if the “collateral damage is children or women — it does not matter to me.”
“In Jenin, there are no innocent civilians,” he added. “In Jenin, there are no innocent children.”
Kroizer was referring to a genuine tragedy: The killing of almost an entire Palestinian family by Israel undercover forces on March 15, near the village of Tammun. The forces opened fire on the family’s car as they returned from a shopping trip. Waed Bani Ohde, her husband Ali, and two of their young children Othman, 7, and Mohammed, 5, were killed. Two sons survived. The army says the car accelerated toward the forces; Palestinian witnesses say the IDF gave no warning before attacking.
It is tempting to dismiss statements like Kroizer’s as the rhetoric of the extreme. Indeed, I often find myself making that point when talking to people inclined to think the worst of Israel: They do not represent the majority, and not even the immoral government of Prime Minister Benjamin Netanyahu.
But that, while true, is becoming a little too pat.
For it is also true that as time goes, as the wars continue and hearts harden, what Kroizer articulated is a moral framework that is steadily taking hold in the Israeli right.
That’s why the statements were not condemned by anyone associated with the government. And, indeed, Israeli far-right activists responded to the deaths with social media posts rejoicing in the death of the unarmed “terrorists.”
No senior Israeli official apologized for the shooting. No one said publicly that even if the soldiers believed they were acting under threat, the killing of two children demands something more than a routine internal review.
No official has even conceded that this type of event might contribute to agitation and instability in the West Bank, and perhaps spark another uprising. Set empathy aside; even enlightened self-interest is beyond the current Israeli government.
Yes, an investigation has been opened. But military investigations almost never lead to concrete action against the troops. A Guardian report this week revealed that no Israeli citizen has been prosecuted for a killing in the West Bank since 2020, despite a radical uptick in violence; settlers and police have already killed 10 Palestinian civilians this month alone.
The undercover soldiers, especially, are something like the real life version of the international hit Fauda, widely admired for their counter-terrorism activity. There is little appetite for throwing the book at them.
So while it’s tempting to chalk this up as just another tragedy in a long list of tragedies on both sides, it is actually much more: a devastating manifestation of something fundamental — not just a personal tragedy but a national one.
That’s a tragedy I’ve seen unfolding slowly, since even before the Hamas attack of Oct. 7, 2023.
I’ve seen it in the rhetoric of far-right leaders like cabinet ministers Itamar Ben-Gvir and Bezalel Smotrich. But I’ve also seen it firsthand, as when I found myself on wartime television panels where I was besieged by right-wingers enraged at my assertion that innocents have been killed during the war in Gaza. I challenged one of them about whether this idea would include a two-week old baby.
“OK, maybe not the baby!” he conceded, unhappily.
The descent of part of Israeli society into this unforgivable lack of compassion is, some have argued, an inevitable outcome of indefinite control over the Palestinian territories. For years, warnings that rule over millions of disenfranchised Arabs would mutate Israel’s character were treated as excessive, even hysterical.
Israel was not a colonial power in the classic sense, its defenders argued; it was a democracy under siege, navigating impossible dilemmas. The West Bank may be “occupied” but that was justifiable because of the threat its near proximity posed. Israel’s actions might be harsh, but they were necessary, the argument went. It was said that the country’s moral core, despite pressures, would remain intact.
The initial signs after this latest tragedy are not exactly reassuring. Far from condemning Kroizer, as they rightly should have, the cabinet convened this week to offer his party a great gift: the legalization of 30 illegal settlement outposts, including some in “Area A,” which is supposed to be under full Palestinian control.
Israel did not begin this way. Its founding story was deeply bound up with an acute awareness of the need to maintain morality. The early Zionists envisioned a country that would be a “light unto the nations.”
As occupation has become an entrenched reality, most Israelis have wanted to look away; the problem is too complicated. This position may not be possible for much longer. The moral rot is too extreme. But the good news is that it has not infected everything and everyone. Israel’s public broadcaster devoted a segment to the Palestinian family’s tragedy, characterizing Kroizer’s statements as a disgrace.
The humanistic ideas through which Israel once judged itself have eroded. We must now hope that they won’t entirely vanish.
