BEIRUT—ISIS terrorists killed more than 200 people in a coordinated assault on a government-held area of southwestern Syria on Wednesday, local officials and a war monitor said, in the group’s deadliest attack in the country for years.
Jihadist fighters stormed several villages and staged suicide blasts in the provincial capital Sweida, near one of the few remote pockets still held by ISIS after it was driven from most of its territory last year.
