DUBAI (Sputnik) — He added that every associated group would respond to government attacks in line with their capacities.
"If attacks on Darayya and besieged areas across Syria continue and the ceasefire regime is violated throughout the country, all groups associated with the Free Syrian Army and other revolutionary units will withdraw from the political process in 48 hours," Abu Zeid told RIA Novosti, commenting on the ongoing clashes between government troops and rebels in Darayya.
Earlier last week, governmental troops liberated towns of Deir al-Asafir and Zebdin in the eastern outskirts of Damascus.
The parties to the Syrian conflict, which erupted in 2011, laid down their arms on February 27. The ceasefire regime across Syria does not apply to territories under the control of terrorist groups.
