DAMASCUS: Syria’s militant chief called on people across the country to celebrate “the victory of the revolution” on Friday, as G7 leaders looked to forge a common approach to the new government.

More than half a century of brutal rule by the Assad clan came to a sudden end on Sunday, after a lightning militant offensive led by Abu Mohammed Al-Golani’s Islamist group Hayat Tahrir Al-Sham (HTS) swept across the country and took the capital.

Ousted president Bashar Assad fled Syria, closing an era in which suspected dissidents were jailed or killed, and capping nearly 14 years of war that killed more than 500,000 people and displaced millions.

“I would like to congratulate the great Syrian people on the victory of the blessed revolution and I call on them to go to the streets to express their joy,” Golani said on Telegram.

Golani, who is now using his real name Ahmed Al-Sharaa, is set to attend Friday prayers at Damascus’s landmark Umayyad Mosque.

During the early days of Syria’s uprising in 2011, protesters would often gather after noon prayers on Fridays, the Muslim day of prayer and rest.

Assad’s overthrow has allowed Syrians to flood to prisons, hospitals and morgues in search of long-disappeared loved ones, hoping for a miracle, or at least closure.

“I turned the world upside down looking,” Abu Mohammed said as he searched for news of three missing relatives at the Mazzeh air base in Damascus.

“But I didn’t find anything at all. We just want a hint of where they were, one percent.”

Sunni Muslim HTS is rooted in Syria’s branch of Al-Qaeda and designated a terrorist organization by many Western governments, who now face the challenge of how to approach the country’s new transitional leadership.

The group has sought to moderate its rhetoric, and the interim government insists the rights of all Syrians will be protected.

The spokesman for the newly installed government, Obaida Arnaout, said that the country’s constitution and parliament would be suspended during a three-month transition.

“A judicial and human rights committee will be established to examine the constitution and then introduce amendments,” he said, pledging that the “rule of law” would be instituted.

Leaders of the Group of Seven countries, who will meet virtually at 1430 GMT on Friday, said they were ready to support the transition to an “inclusive and non-sectarian” government in Syria.

They called for the protection of human rights, including those of women and minorities, while emphasizing “the importance of holding the Assad regime accountable for its crimes.”

Inside much of Syria, the focus for now is on unraveling the secrets of Assad’s rule, and particularly the network of detention centers and suspected torture sites scattered across areas previously under government control.

Syria’s leadership said it is willing to cooperate with Washington in the search for US citizens who disappeared under Assad’s rule, including US journalist Austin Tice, who was abducted in 2012.

Another American, Travis Timmerman, has already been located alive and Blinken said Washington was working to bring him home.

The search for other missing detainees has ended more painfully, with hundreds of Syrians gathering Thursday to bury outspoken activist Mazen Al-Hamada.

In exile in the Netherlands, he publicly testified on the torture he was subjected to in Syrian prison.

He later returned to Syria and was detained. His body was among more than 30 found in a Damascus hospital morgue this week.

Assad was propped up by Russia — where a senior Russian official told US media he has fled — as well as Iran and Lebanon’s Hezbollah militant group.

The militants launched their offensive on November 27, the same day a ceasefire took effect in the Israel-Hezbollah war, which saw Israel inflict staggering losses on Assad’s Lebanese ally.

Both Israel and Turkiye, which backs some of the militants who ousted Assad, have since carried out strikes inside Syria.

The fall of Assad has prompted some of the millions of Syrians who fled abroad to return home.

On Friday morning, around 60 people were waiting at Turkiye’s Oncupinar border crossing, anxious to reach Syria.

In the southern city of Sweida, the heartland of Syria’s Druze minority where anti-government demonstrations have been held for more than a year, hundreds took to the streets on Friday, singing and clapping in jubiliation.

“Our joy is indescribable,” said Haitham Hudeifa, 54. “Every province is celebrating this great victory.”
