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.

Syria Tightens Grip After Kurdish Pullback, Says Islamic State Prisoners Escape

Syrian government troops tightened their grip on Monday across a swathe of northern and eastern territory after it was abruptly abandoned by Kurdish forces in a dramatic shift that has consolidated President Ahmed al-Sharaa’s rule.
A day after the Kurdish-led Syrian Democratic Forces (SDF), once the main US ally in Syria, agreed to quit large areas under a ceasefire, the Syrian army said “a number of” Islamic State terrorists had escaped a prison that had been under SDF control in the eastern city of Shaddadi, accusing the SDF of releasing them.
The SDF said it had lost control of the prison following an attack by government fighters. The Syrian army denied attacking the jail and said its forces would work to secure the prison and re-arrest the escapees.
The SDF said Shaddadi prison had held thousands of militants. The army did not say how many IS detainees had fled.
The SDF withdrawals mark the biggest change in Syria‘s control map since Islamist fighters led by Sharaa toppled President Bashar al-Assad in 2024, tilting the power balance Sharaa’s way after months of deadlock in talks with the SDF over government demands its forces merge fully with Damascus.
After days of fighting with government forces, the SDF agreed on Sunday to withdraw from both Raqqa and Deir al-Zor – two Arab-majority provinces they had controlled for years and the location of Syria‘s main oil fields.
GOVERNMENT TROOPS DEPLOY AT OILFIELD, IN RAQQA
Turkey, which has repeatedly sent forces into northern Syria to curb Kurdish power since 2016, welcomed the deal signed by its ally Sharaa and SDF commander Mazloum Abdi. Turkish President Tayyip Erdogan urged the swift implementation of the agreement that requires the full integration of Kurdish fighters into Syria‘s armed forces.
The SDF, spearheaded by the Kurdish YPG militia, had established control of a quarter or more of Syria during the 2011-2024 civil war, whilst fighting with the support of US troops against Islamic State. The United States, which has since established close ties with Sharaa under President Donald Trump, has been closely involved in mediation between the sides.
The SDF media office said in a statement that the prison at Shaddadi – one of three under its control in the Hasakah region – had come under repeated attack by “Damascus factions,” and that dozens of SDF fighters were killed or wounded defending it.
The statement added that the US-led coalition against Islamic State had not intervened despite repeated appeals to a nearby coalition base. The US military’s Central Command did not immediately respond to an emailed request for comment.
In its denial of the SDF account, the Syrian Ministry of Defense said army forces had bypassed Shaddadi, in line with deployment plans, and offered aid to SDF forces inside. The Syrian army announced it had established control over the city of Shaddadi and the prison.
The Syrian Defense Ministry also denied an SDF account of clashes between government and SDF forces near a jail in Raqqa, which the SDF said was holding IS inmates. It said the army had arrived “at the vicinity of al-Aqtan prison … and began securing it and its surroundings despite the presence of SDF forces inside”.
The SDF said nine of its fighters were killed and 20 wounded in clashes around al-Aqtan.
Hasakah province, which largely remains under SDF control, is home to the Kurdish-majority city of Qamishli, the main prisons holding Islamic State detainees, and a camp holding thousands of IS-linked prisoners.
GOVERNMENT FORCES DEPLOY
Reuters journalists saw government forces deployed in the city of Raqqa that the SDF had captured from Islamic State in 2017, and at oil and gas facilities in the eastern province of Deir al-Zor – both areas the Kurdish forces had held for years.
It follows the withdrawal of Kurdish forces from districts of Aleppo city they had controlled for years after fighting there earlier this month.
The 14-point deal published by Syria‘s presidency showed Abdi’s signature alongside Sharaa’s.
It stipulates that the prisons, along with all border crossings and oil and gas fields, would be handed to government control – steps the SDF had long resisted.
The timing of the handover of the prisons and camps was not announced.
Abdi, the SDF commander, confirmed on Sunday that the SDF had agreed to withdraw from Deir al-Zor and Raqqa provinces.
Abdi said he is set to meet Sharaa in Damascus on Monday and would share the details of the agreement with the public after his return to SDF-held territory, Kurdish media reported.
The deal says that all SDF forces will be merged into the defense and interior ministries as “individuals” and not as units, as the SDF had sought.
It commits the SDF to expel all non-Syrian figures affiliated to the Kurdistan Workers’ Party (PKK), a Kurdish militant group which fought a decades-long insurgency in Turkey.
Senior figures from Erdogan’s ruling AK Party said this removed a major obstacle to Turkey’s peace process with PKK militants.

Israeli Government Sends 2026 Budget to Parliament, Approval at Risk From Rifts

Israel’s Finance Ministry said on Monday it delivered the 2026 state budget draft to parliament ahead of a preliminary vote on Wednesday, though the plan’s prospects are clouded by political fractures that have strained the ruling coalition.
Delayed by political infighting, the cabinet last month approved the spending plan for this year after defense outlays were raised to 112 billion shekels ($35.45 billion) from an initial 90 billion.
The budget, as well as an accompanying economic plan, faces an uphill battle for approval as the government has become increasingly polarized. By law it must be approved by the end of March or an election would be triggered.
If approved on Wednesday, the budget will head to parliament‘s finance committee where it could undergo changes before its final two votes in the plenum.
For more than two years parties in the ruling coalition have splintered over the war in Gaza, the ceasefire that has halted it, and demands by ultra-Orthodox Jewish parties to exempt Jewish seminary students from mandatory military service.
In all, state spending would be 662 billion shekels excluding debt servicing. The deficit ceiling was set at 3.9% of gross domestic product, a level the Bank of Israel deems as too high since it does not allow for a reduction in the debt burden.
The budget deficit slipped to 4.7% of GDP in 2025 from 6.8% in 2023. A spike in defense costs due to the Gaza war pushed the deficit higher the past two years.
While the ceasefire has halted most fighting, it has not stopped entirely, and both sides have accused one another of violating the deal’s provisions.

Iran to Consider Lifting Internet Ban as Brutal Crackdown Quells Protests; State TV Hacked

Iran may lift its internet blackout in a few days, a senior parliament member said on Monday, after authorities shut communications while they used massive force to crush protests in the worst domestic unrest since the 1979 Islamic Revolution.
In the latest sign of weakness in the authorities’ control, state television appeared to be hacked late on Sunday, briefly showing speeches by US President Donald Trump and the exiled son of Iran‘s last shah calling on the public to revolt.
Iran‘s streets have largely been quiet for a week, authorities and social media posts indicated, since anti-government protests that began in late December were put down in three days of mass violence.
An Iranian official told Reuters on condition of anonymity that the confirmed death toll was more than 5,000, including 500 members of the security forces, with some of the worst unrest taking place in ethnic Kurdish areas in the northwest. Western-based Iranian rights groups also say thousands were killed.
ARRESTS REPORTED TO BE CONTINUING
US-based Iranian Kurdish rights group HRANA reported on Monday that a significant number of injuries to protesters came from pellet fire to the face and chest that led to blindings, internal bleeding, and organ injuries.
State television reported arrests continuing across Iran on Sunday, including Tehran, Kerman in the south, and Semnan just east of the capital. It said those detained included agents of what it called Israeli terrorist groups.
Opponents accuse the authorities of opening fire on peaceful demonstrators to crush dissent. Iran‘s clerical rulers say armed crowds encouraged by foreign enemies attacked hospitals and mosques.
The death tolls dwarf those of previous bouts of anti-government unrest put down by the authorities in 2022 and 2009. The violence drew repeated threats from Trump to intervene militarily, although he has backed off since the large-scale killing stopped.
Trump’s warnings raised fears among Gulf Arab states of a wider escalation, and they conducted intense diplomacy with Washington and Tehran. Iran‘s ambassador to Saudi Arabia Alireza Enayati said on Monday that “igniting any conflict will have consequences for the entire region.”
INTERNET TO RETURN WHEN ‘CONDITIONS ARE APPROPRIATE’
Iranian communications including internet and international phone lines were largely stopped in the days leading up to the worst unrest. The blackout has since partially eased, allowing accounts of widespread attacks on protesters to emerge.
The internet monitoring group Netblocks said on Monday that metrics showed national connectivity remained minimal, but that a “filternet” with managed restrictions was allowing some messages through, suggesting authorities were testing a more heavily filtered internet.
Ebrahim Azizi, the head of parliament’s National Security and Foreign Policy Committee, said top security bodies would decide on restoring internet in the coming days, with service resuming “as soon as security conditions are appropriate.”
Another parliament member, hardliner Hamid Rasaei, said authorities should have listened to earlier complaints by Supreme Leader Ali Khamenei about “lax cyberspace.”
During Sunday’s apparent hack into state television, screens broadcast a segment lasting several minutes with the on-screen headline “the real news of the Iranian national revolution.”
It included messages from Reza Pahlavi, the US-based son of Iran‘s last shah, calling for a revolt to overthrow rule by the Shi’ite Muslim clerics who have run the country since the 1979 revolution that toppled his father.
Pahlavi has emerged as a prominent opposition voice and has said he plans to return to Iran, although it is difficult to assess independently how strong support for him is inside Iran.
