In this video Jaish al-Muslimin brigade claims they have targeted the Syrian Air Force intelligence depatrment in strategic Harastah by mortars.

Harastah lies on the main highway between Damascus and Homs. The rebels need to control the town to link Eastern Ghouta with Western Ghouta in Outer Damascus and to isolate the government in the capital. Video courtesy of Lewa Jaishalmouslemin YouTube channel
