WASHINGTON: The head of a US-based Syrian advocacy organization on Monday said that a mass grave outside of Damascus contained the bodies of at least 100,000 people killed by the former government of ousted President Bashar Assad.
Mouaz Moustafa, speaking to Reuters in a telephone interview from Damascus, said the site at al Qutayfah, 25 miles (40 km) north of the Syrian capital, was one of five mass graves that he had identified over the years.
“One hundred thousand is the most conservative estimate” of the number of bodies buried at the site, said Moustafa, head of the Syrian Emergency Task Force. “It’s a very, very extremely almost unfairly conservative estimate.”
Moustafa said that he is sure there are more mass graves than the five sites, and that along with Syrians victims included US and British citizens and other foreigners.
Reuters was unable to confirm Moustafa’s allegations.
Hundreds of thousands of Syrians are estimated to have been killed since 2011, when Assad’s crackdown on protests against his rule grew into a full-scale civil war.
Assad and his father Hafez, who preceded him as president and died in 2000, are accused by Syrians, rights groups and other governments of widespread extrajudicial killings, including mass executions within the country’s notorious prison system.
Assad repeatedly denied that his government committed human rights violations and painted his detractors as extremists.
Syria’s UN Ambassador Koussay Aldahhak did not immediately respond to a request for comment. He assumed the role in January — while Assad was still in power — but told reporters last week that he was awaiting instructions from the new authorities and would “keep defending and working for the Syrian people.”
Moustafa arrived in Syria after Assad flew to Russia and his government collapsed in the face of a lightning offensive by rebels that ended his family’s more than 50 years of iron-fisted rule.
He spoke to Reuters after he was interviewed at the site in al Qutayfah by Britain’s Channel 4 News for a report on the alleged mass grave there.
He said the intelligence branch of the Syrian air force was “in charge of bodies going from military hospitals, where bodies were collected after they’d been tortured to death, to different intelligence branches, and then they would be sent to a mass grave location.”
Corpses also were transported to sites by the Damascus municipal funeral office whose personnel helped unload them from refrigerated tractor-trailers, he said.
“We were able to talk to the people who worked on these mass graves that had on their own escaped Syria or that we helped to escape,” said Moustafa.
His group has spoken to bulldozer drivers compelled to dig graves and “many times on orders, squished the bodies down to fit them in and then cover them with dirt,” he said.
Moustafa expressed concern that graves sites were unsecured and said they needed to be preserved to safeguard evidence for investigations.

UNITED NATIONS: United Nations aid chief Tom Fletcher met with the commander of Syria’s new administration, Ahmed Al-Sharaa, and newly appointed Prime Minister Mohammed Al-Bashir on Monday to discuss scaling up humanitarian assistance in the country.
Following Fletcher’s meeting, UN Secretary-General Antonio Guterres said in a statement that he welcomed the caretaker government’s commitment to protect civilians, including humanitarian workers.
“I also welcome their agreement to grant full humanitarian access through all border crossings; cut through bureaucracy over permits and visas for humanitarian workers; ensure the continuity of essential government services, including health and education; and engage in genuine and practical dialogue with the wider humanitarian community,” Guterres said.
Syria’s Bashar Assad was ousted after insurgent forces led by the Islamist Hayat Tahrir Al-Sham swept through Syria in a lightning offensive, ending more than 50 years of iron-fisted rule by his family.
Guterres called on the international community to rally behind the Syrian people as they “seize the opportunity to build a better future.” The United Nations says seven in 10 people in Syria continue to need humanitarian aid.
Fletcher also plans to visit Lebanon, Turkiye and Jordan, UN spokesperson Stephane Dujarric said. (Reporting by Michelle Nichols Editing by Bill Berkrot)
