IS fighters evacuated from southern Damascus: monitor
The Syrian Observatory for Human Rights said the militants and their families had been bused out of the Palestinian refugee camp Yarmouk and neighbouring Tadamun district, restoring state control over the area.
"The six buses left at dawn, heading east for the Syrian desert," Observatory head Abdel Rahman told AFP.
Syrian state media has not reported a deal to allow the militants to leave the enclave. On Saturday, a Syrian military source denied that any agreement had been reached, state media said.
The Observatory on Saturday said the two factions observed a brief ceasefire, which could have been a prelude to the evacuation of IS fighters from the area.
Syrian regime forces have conducted a devastating bombing campaign on the IS-held camp which has been subjected to fierce fighting and heavy losses on both sides.
Yarmouk was once a densely populated and thriving district of the capital, but it has been ravaged by violence since Syria's conflict broke out in 2011.
