"During the military operations and our forces' advancement towards Mleiha village, Syrian Armed forces found some tunnels, among which is this tunnel with a width of two meters and a height of 1.5 meters. This tunnel is used by the armed men to move arms and supplies."

Syrian government troops have gained momentum following the collapse of U.S.-backed peace talks.
