Late on Friday, Islamic State began releasing some of the scores of cement-plant workers they kidnapped northeast of Damascus this week, the Syrian Observatory for Human Rights monitoring group said.
Local municipality officials in two nearby towns managed to secure an agreement for IS to release 170 workers it had been holding since Wednesday, the Britain-based Observatory said.
IS seized the workers after launching an attack on Syrian government forces in the area where the cement plant is located, near the town of Dumeir.
Syrian state media said IS had kidnapped 300 workers and contractors. The Observatory said 140 workers had fled before the terrorists arrived.
IS’s Amaq news agency said on Friday that the group freed nearly 300 workers but had executed four of them for being from the Druze minority.
