ISIS kidnapped dozens of women and children when it attacked their villages last week in Syria's southern province of Sweida, the Syrian Observatory for Human Rights said Monday.
More than 250 people were killed on Wednesday when the terrorist group carried out a string of suicide attacks and shootings in the provincial capital Sweida and villages to the north and east.
"At least 36 Druze women and children were abducted after the attacks," said the Britain-based monitor.
Four of the women had since managed to escape and another two had died, said Observatory chief Rami Abdel Rahman.
Another 17 men from the areas targeted by ISIS were still unaccounted for, but it was unclear if they were also kidnapped, he told AFP.
Both the Observatory and Syrian news outlet Sweida24 said 20 women and 16 children had been kidnapped.
ISIS has so far not claimed the kidnappings, and no details on them could be found on its propaganda channels.
The extremist group still holds small, isolated areas of Syria's remote desert, which includes northeastern parts of Sweida, as well as pockets in the adjacent province of Daraa and further east near the border with Iraq.
