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.

London Jewish Community Feels ‘Anxious’ but ‘Resilient’ as It Prepares for Potential Future Attacks

The Jewish community in London is feeling “very anxious” while trying to stay vigilant and prepared for potential incidents in the future after four Hatzalah emergency vehicles were destroyed in an antisemitic arson attack last week, the president of the UK’s main Jewish umbrella organization said on Sunday.
“We’ve had two-and-a half-years of very high levels of antisemitism, obviously, the deadly attack at Heaton Park Synagogue in Manchester just in October, and now this incident, an arson attack in the heart of London’s Jewish community in Golders Green,” Phil Rosenberg of the Board of Deputies of British Jews said during an appearance on “BBC London Politics.”
“It is nonetheless a very resilient and proud community, and we are looking at how we push back and build back stronger,” Rosenberg added.
Roughly 150,000 Jewish people live in London.
Rosenberg, a deputy at a north London synagogue and former Labour councillor in Camden, was also asked about the British government’s response to the arson attack. He said that, with help from the government, the Jewish community in London is now equipped with specialist kits designed to help during future attacks, including equipment that could help with chemical exposure. The equipment was provided through a £28.4 million government grant to the Community Security Trust (CST), a Jewish charity that safeguards the safety and security of Jews across the UK.
“On the way here, I was looking at my WhatsApps. I saw one come in from my synagogue, and it was talking not about the great services we put on, the outreach to local communities, the wonderful art and charity that we do, but about a series of kits we’ve just received that will help the community if there’s an attack to stem the flow of blood, or if there’s a chemical attack. That is the situation we’re facing,” Rosenberg explained.
“It’s sad that it’s needed, though,” he added. “Because what we need to do is prevent this and create a situation where those things are not the things we’re talking about, and those are not the things we need. We want to be celebrating the Jewish community, and all communities in this city, and not [be] in fear of those sorts of attacks happening.”
Last year, there were over 1,800 antisemitic incidents in London, according to data compiled by CST. When asked if the Jewish community believes the government is doing enough to tackle the issue of antisemitism, Rosenberg said the response is “mixed.” He noted the speed at which the British government provided replacements vehicles for the Hatzalah ambulances destroyed last week and other moves by the government, like proscribing the pro-Hamas group Palestine Action.
“The government still needs to go further,” Rosenberg added, before calling for British leaders to proscribe Iran’s Islamic Revolutionary Guard Corps and to take more action to combat hatred flourishing on social media, among other issues.
“We’ve seen in our society a growth of extremism … and we are very concerned that we are seeing society being pulled apart,” he said. “We need to come together, among all communities, to push back against hatred in all its forms, including antisemitism, and marginalize those extremists.”

Antisemitic Acts in Australia Persist With Car Attack, Statue Vandalism

Law enforcement in Australia has launched investigations into multiple recent antisemitic incidents, including a car attack on Hasidic men on Saturday and the vandalism earlier this month of a statue honoring an Australian Jewish feminist.
The Victoria branch of the Community Security Group (CSG), an organization focused on protecting local Jews, released a statement on Saturday alerting the community of an incident in Melbourne “on Glen Eira Road, Ripponlea, where a vehicle swerved towards community members while occupants shouted antisemitic remarks.”
The CSG reported that “Victoria Police patrols were active in the area and responded to the scene rapidly. There are no reports of physical injuries. CSG is liaising closely with police and continuing to monitor the situation.”
Ripponlea has a significant Haredi population with members of the Adass Israel community comprising 15.2 percent of the population. The neighborhood has seen other recent antisemitic incidents, including the bombing of the group’s synagogue in December 2024.
The suspects — four women — allegedly drove a black Hyundai stolen on Wednesday from a home in the Caulfield suburb. Victoria police confirmed they had opened an investigation and received reports of other incidents involving the antisemitic occupants driving erratically and throwing eggs at people while yelling abuse.
“Those responsible are brazen, bold, and appear to act with impunity,” Naomi Levin, the CEO of the Jewish Community Council of Victoria (JCCV), told The Australian.
On Friday, Victoria Police announced the arrests of seven women alleged to have vandalized the statue of Zelda D’Aprano — a Jewish Australian feminist — outside the Victorian Trades Hall on March 6 at approximately 11:00 am.
In a statement, law enforcement described the women as part of an activist group and listed their ages as ranging between 34 and 71. The police stated that security footage showed that the vandals pulled out umbrellas to conceal their identities as they sprayed black and red paint on the statue. They also hung a “difficult woman” apron.
D’Aprano worked as an advocate for women’s rights from the 1950s through the 1980s and co-founded the Women’s Action Committee in 1970. She was known to have chained herself to a government building in 1969 to advocate equal pay for women. Her statue was unveiled in 2023.
The activists face charges of “criminal damage, behaving in a riotous manner in a public place, marking graffiti on a residence without consent, recklessly damaging part of a registered place without a permit, and refusing to leave scheduled public place after a warning.” An eighth suspect remains at large.
So far, the only named suspect is Jemima Demanuele, 34, who appeared in a Melbourne court on Friday and was reportedly on bail for another protesting offense.
Victoria Police officer Tiffany Lamesta pushed back on releasing Demanuele, saying that “the accused has been given bail for the last incident but is showing no respect for court orders” and warning that “police believe the accused will continue to offend if she’s granted bail.”
Demanuele is currently on paid leave from her position at St Vincent’s Hospital as staff conduct a Fair Work investigation.
Magistrate Michelle Hodgson granted Demanuele bail and instructed her that “there is no issue with protest, but it must be lawful, it must not endanger the safety and welfare of other persons and it must not cause property damage.”
Police have not yet stated a motive for the vandalism. Photographs from the scene show multiple members of the group wearing black and white keffiyehs, the symbol of anti-Israel militancy popularized by the late Palestinian leader Yasser Arafat.
Antisemitism surged in Australia following Hamas’s Oct. 7, 2023, terrorist attacks across southern Israel. On Feb. 24, Australia announced the creation of a Royal Commission led by retired judge Virginia Bell to investigate antisemitism in the country following the murder of 15 Jews at Bondi Beach in December.
Bell said that the commission needs to “investigate the security arrangements for that event, and to report on whether our intelligence and law enforcement agencies performed to maximum effectiveness.”
Australia’s intelligence authorities revealed last year that the Islamic regime in Iran had directed antisemitic acts in the country using cryptocurrency to compensate criminals, prompting the expulsion of Iran’s Ambassador Ahmad Sadeghi and three other officials.
On Friday, the CSG and JCCV released an annual report on antisemitism in Australia’s Victoria state, documenting 564 incidents, the highest number ever recorded.
“Behind each of these reports is a Jewish person,” Levin said. “A child in school uniform abused on a school excursion, a man in a kippah verbally abused on public transport, a worshipper arriving at synagogue to find hateful words painted on its walls, a business owner wiping racist symbols off their window before opening for the day.”

French Authorities Foil, Probe Paris Bomb Plot in One of Europe’s Latest Suspected Iran-Linked Attacks

French authorities are investigating a suspected link to Iran after foiling a bomb attack outside a Bank of America building in Paris over the weekend, in one of the latest terrorist plots to heighten fears of further Iran-linked attacks across Europe amid war in the Middle East.
On Monday, French Interior Minister Laurent Nuñez confirmed investigators are looking into a possible connection to Iran, citing similarities between the foiled attack and a string of recent attempted terrorist plots across Europe claimed by a pro‑Iran group.
“Authorities are drawing a direct link to Iran, since the modus operandi mirrors attacks recently carried out in the Netherlands and Belgium,” Nuñez told the French radio station RTL, referring to a synagogue set ablaze in Rotterdam and another damaged in an explosion in Liège earlier this month.
Known as Harakat Ashab al-Yamin al-Islamia, which translates to the Islamic Movement of the Companions of the Right, the group has also taken responsibility for a shocking attack in London last week, torching four ambulances belonging to a Jewish community organization.
Although no government has formally acknowledged or verified the existence of the group or its alleged operations, the repeated claims have raised concerns about a potentially coordinated network targeting Jewish communities across Europe amid heightened tensions and fears of Iranian retaliation and possible sleeper-cell activity linked to the war in the Middle East.
In this latest incident, local police in Paris spotted two suspects on Saturday near the Bank of America building in the city’s 8th arrondissement — a central district near major government offices and embassies — just moments after they had planted a homemade explosive device, with one of the men preparing to ignite it with a lighter.
Shortly after authorities thwarted the attempted attack, France’s anti-terrorism prosecutor’s office opened an investigation for “attempted damage by fire or dangerous means in connection with a terrorist enterprise.”
Since then, five suspects — including three minors and two adults — have been arrested on alleged terrorism-related offenses as investigators work to determine whether the plot was coordinated from abroad and linked to a wider network.
According to French media reports, the suspects were recruited via Snapchat and offered 600 euros to carry out the operation — a tactic officials say reflects a modus operandi increasingly used by Iranian intelligence services to operate indirectly and discreetly without formally implicating Tehran.
“Typically, Iran’s intelligence services operate in this way: They use proxies, a series of subcontractors, often common criminals, to carry out highly targeted actions aimed at US interests, the interests of the Jewish community, or Iranian opposition figures,” Nuñez said.
As the US–Israeli war with Iran continues to escalate, Nuñez also said authorities have dramatically ramped up security around key figures and sensitive sites, including providing personal protection to some Iranian opposition members.
