DAMASCUS — Syrian rebel forces have said they plan to close the notoriously harsh prisons run by ousted president Bashar al-Assad and hunt those involved in the killing or torture of detainees.

Rebel leader Ahmed al-Sharaa, also known as Abu Mohammed al-Jolani, also said he would dissolve the security forces of the former regime, in a statement seen by the Reuters news agency.

Videos showing thousands of prisoners being freed from Saydnaya prison — referred to as a "human slaughterhouse" by rights groups — surfaced after the collapse of the Assad government on Sunday.

Almost 60,000 people were tortured and killed in the prisons run by Assad, UK-based monitoring group Syrian Observatory for Human Rights said.

Jolani's Islamist militant group, Hayat Tahrir al-Sham (HTS), led other Syrian rebel factions in a lightning offensive that toppled the Assad dynasty's 54-year-rule.

Assad fled to Russia in the early hours of Sunday, where he and his family have been given asylum, after rebels captured the capital Damascus.

In a separate statement, Jolani said pardons for those who took part in the torture or killing of prisoners were out of the question.

"We will pursue them in Syria, and we ask countries to hand over those who fled so we can achieve justice," he said.

Since the fall of President Bashar al-Assad Syrians have rushed to the regime's infamous prisons, desperately searching for their loved ones. In a 2022 report, the Turkey-based Association of Detainees and The Missing in Saydnaya Prison (ADMSP) said Saydnaya "effectively became a death camp" after the start of the civil war in 2011.

Jolani also said he would dissolve the former Assad regime's security forces. It is not clear how quickly they could be reconstituted by rebel fighters amid concerns about Israeli strikes on the country's military infrastructure. — BBC
