(CNN)ISIS has claimed responsibility for a horrific day of carnage that devastated southern Syria on Wednesday.
ISIS says it's behind the attacks in Syria that killed 166
At least 166 people were killed in a suicide bombing and attacks that took place in the southern province of Suwayda, the United Nations Office for the Coordination of Humanitarian Affairs in Syria tweeted.
ISIS said it was responsible, in a statement posted on the ISIS-affiliated Telegram channel. ISIS said "soldiers of the caliphate" first attacked security positions and government targets in Suwayda city. After the attackers ran out of ammunition, they detonated their explosive vests, ISIS said.
One suicide bombing at a vegetable market killed 38 people, the state-run Ikhbariya TV reported.
State TV showed footage of charred bodies, damaged vehicles and a blown-up street market.
Syrian forces thwarted two other attacks in As-Suwayda, shooting and killing two attackers before they blew themselves up, state-run media added.
In recent weeks, Syrian forces have intensified an offensive in southern Syria to eliminate ISIS pockets that remain in the area. A well-known rescue group called the White Helmets say they have been caught in the crossfire.
