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.

Cuba Defiant After Trump Says Island to Receive No More Venezuelan Oil or Money

US President Donald Trump on Sunday said no more Venezuelan oil or money will go to Cuba and suggested the Communist-run island should strike a deal with Washington, ramping up pressure on the long-time US nemesis and provoking defiant words from the island’s leadership.
Venezuela is Cuba’s biggest oil supplier, but no cargoes have departed from Venezuelan ports to the Caribbean country since the capture of Venezuelan President Nicolas Maduro by US forces in early January amid a strict US oil blockade on the OPEC country, shipping data shows.
Meanwhile, Caracas and Washington are progressing on a $2 billion deal to supply up to 50 million barrels of Venezuelan oil to the US with proceeds to be deposited in US Treasury-supervised accounts, a major test of the emerging relationship between Trump and interim President Delcy Rodriguez.
“THERE WILL BE NO MORE OIL OR MONEY GOING TO CUBA – ZERO! I strongly suggest they make a deal, BEFORE IT IS TOO LATE,” Trump wrote on his Truth Social platform on Sunday.
“Cuba lived, for many years, on large amounts of OIL and MONEY from Venezuela,” Trump added.
Cuban President Miguel Diaz-Canel rejected Trump’s threat on social media, suggesting the US had no moral authority to force a deal on Cuba.
“Cuba is a free, independent, and sovereign nation. Nobody dictates what we do,” Diaz-Canel said on X. “Cuba does not attack; it has been attacked by the US for 66 years, and it does not threaten; it prepares, ready to defend the homeland to the last drop of blood.”
The US president did not elaborate on his suggested deal.
But Trump’s push on Cuba represents the latest escalation in his move to bring regional powers in line with the United States and underscores the seriousness of the administration’s ambition to dominate the Western Hemisphere.
Trump’s top officials, including Secretary of State Marco Rubio, have made no secret of their expectation that the recent US intervention in Venezuela could push Cuba over the edge.
US officials have hardened their rhetoric against Cuba in recent weeks, though the two countries have been at odds since former leader Fidel Castro’s 1959 revolution.
CUBA DEFENDS IMPORT RIGHTS
Cuban Foreign Minister Bruno Rodriguez said in another post on X on Sunday that Cuba had the right to import fuel from any suppliers willing to export it. He also denied that Cuba had received financial or other “material” compensation in return for security services provided to any country.
Thirty-two members of Cuba’s armed forces and intelligence services were killed during the US raid on Venezuela. Cuba said those killed were responsible for “security and defense” but did not provide details on the arrangement between the two long-time allies.
Cuba relies on imported crude and fuel mainly provided by Venezuela, and Mexico in smaller volumes, purchased on the open market to keep its power generators and vehicles running.
As its operational refining capacity dwindled in recent years, Venezuela’s supply of crude and fuel to Cuba has fallen. But the South American country is still the largest provider with some 26,500 barrels per day exported last year, according to ship tracking data and internal documents of state-run PDVSA, which covered roughly 50 percent of Cuba’s oil deficit.
Havana produce vendor Alberto Jimenez, 45, said Cuba would not back down in the face of Trump’s threat.
“That doesn’t scare me. Not at all. The Cuban people are prepared for anything,” Jimenez said.
It’s hard for many Cubans to imagine a situation much worse. The island’s government has been struggling to keep the lights on. A majority live without electricity for much of the day, and even the capital Havana has seen its economy crippled by hours-long rolling blackouts.
Shortages of food, fuel and medicine have put Cubans on edge and have prompted a record-breaking exodus, primarily to the United States, in the past five years.
MEXICO BECOMES KEY SUPPLIER
Mexico has emerged in recent weeks as a critical alternative oil supplier to the island, but the supply remains small, according to the shipping data.
Mexican President Claudia Sheinbaum last week said her country had not increased supply volumes, but given recent political events in Venezuela, Mexico had turned into an “important supplier” of crude to Cuba.
US intelligence has painted a grim picture of Cuba’s economic and political situation, but its assessments offer no clear support for Trump’s prediction that the island is “ready to fall,” Reuters reported on Saturday, citing three people familiar with the confidential assessments.
The CIA’s view is that key sectors of the Cuban economy, such as agriculture and tourism, are severely strained by frequent blackouts, trade sanctions and other problems. The potential loss of oil imports and other support from Venezuela could make governing more difficult for Diaz-Canel.
Havana resident and parking attendant Maria Elena Sabina, a 58-year-old born shortly after Castro took power, said it was time for Cuba’s leaders to make changes amid so much suffering.
“There’s no electricity here, no gas, not even liquefied gas. There’s nothing here,” Sabina said. “So yes, a change is needed, a change is needed, and quickly.”

NATO Should Launch Operation to Boost Security in Arctic, Belgian Minister says

NATO should launch an operation in the Arctic to address US security concerns, Belgium’s defense minister told Reuters on Sunday, urging transatlantic unity amid growing European unease about US President Donald Trump’s push to take control of Greenland.
“We have to collaborate, work together and show strength and unity,” Theo Francken said in a phone interview, adding that there is a need for “a NATO operation in the high north.”
Trump said on Friday that the US needs to own Greenland to prevent Russia or China from occupying it in the future.
European officials have been discussing ways to ease US concerns about security around Greenland, an autonomous territory of the Kingdom of Denmark.
Francken suggested NATO’s Baltic Sentry and Eastern Sentry operations, which combine forces from different countries with drones, sensors and other technology to monitor land and sea, as possible models for an “Arctic Sentry.”
He acknowledged Greenland‘s strategic importance but said “I think that we need to sort this out like friends and allies, like we always do.”
A NATO spokesperson said on Friday that alliance chief Mark Rutte spoke with US Secretary of State Marco Rubio about the importance of the Arctic for shared security and how NATO is working to enhance its capabilities in the high north.
Denmark and Greenland‘s leaders have said that the Arctic island could not be annexed and international security did not justify such a move.
The US already has a military presence on the island under a 1951 agreement.

IDF Strikes Hezbollah Weapons Sites in Lebanon After Army Denied Its Existence

i24 News – The Israel Defense Forces carried out airstrikes on a site in southern Lebanon that the Lebanese Army had previously declared free of Hezbollah activity, Israeli officials said on Sunday, citing fresh intelligence that contradicted Beirut’s assessment.
According to Israeli sources, the targeted location in the Kfar Hatta area contained significant Hezbollah weapons infrastructure, despite earlier inspections by the Lebanese Armed Forces (LAF) that concluded no military installations were present.
Lebanese officials had conveyed those findings to international monitoring mechanisms, and similar claims were reported in the Lebanese newspaper Al-Akhbar.
Israeli intelligence assessments, however, determined that Hezbollah continued to operate from the site.
During a second wave of strikes carried out Sunday, the IDF attacked and destroyed the location.
Video footage released afterward showed secondary explosions, which Israeli officials said were consistent with stored weapons or munitions at the site.
The IDF stated that the strike was conducted in response to what it described as Hezbollah’s ongoing violations of ceasefire understandings between Israel and Lebanon. Military officials said the targeted structure included underground facilities used for weapons storage.
According to the IDF, the same site had been struck roughly a week earlier after Israel alerted the Lebanese Army to what it described as active terrorist infrastructure in the area. While the LAF conducted an inspection following the warning, Israeli officials said the weapons facilities were not fully dismantled, prompting Sunday’s follow-up strike.
The IDF said it took measures ahead of the attack to reduce the risk to civilians, including issuing advance warnings to residents in the surrounding area.
“Hezbollah’s activity at these sites constitutes a clear violation of the understandings between Israel and Lebanon and poses a direct threat to the State of Israel,” the military said in a statement.
Israeli officials emphasized that operations against Hezbollah infrastructure would continue as long as such threats persist, underscoring that Israel retains the right to act independently based on its own intelligence assessments.
