Resistance fighters and Syrian army continued closing in on the strategic city of Zabadani near the Lebanese border.
The Syrian army and Hezbollah managed to put the city under full fire-range and cut off all supply lines of armed groups, according to the Syrian Observatory.
The militants tried to counterattack several times but their attempts were thwarted and they sustained huge losses.
Earlier, Hezbollah and the Syrian army took over a number of residential areas in the Sultani neighborhood in the southern part of the town and reached Jameh al-Huda district.
Gunmen were trapped in central Zabadani and the whole area was within the fire-range of the forces.
Thus, armed groups had lost an important stronghold, which was a point of weakness to the security of the Syrian capital.
