At least 20 members of regime security forces and 14 rebels were killed in an attack today on an intelligence headquarters in Syria's second city Aleppo, a monitor said.
The attack, which began with a powerful bomb blast in a tunnel targeting air force intelligence offices in Aleppo, was aimed at seizing the building but failed, the Syrian Observatory for Human Rights said.
Sporadic fighting was continuing in the area, it said, but heavy clashes had subsided.
