Dozens were killed Wednesday when Syrian rebels set off a powerful tunnel explosion targeting an intelligence headquarters in Aleppo and clashed with regime forces, a monitor said.
The Syrian Observatory for Human Rights said the blast hit a building housing the air force intelligence offices in the west of Syria’s second city and was followed by heavy clashes, reports AFP.
“The explosion and the fighting caused dozens of deaths on both sides,” the Britain-based group said, adding that part of the building had collapsed.
At least 20 regime forces and 14 rebels were killed in the fighting according to the monitoring group. They added that the attempt to conquer the regime headquarters failed, and sporadic fighting had started to dwindle.
