"The negotiations process, on its current basis, is meaningless in light of the ongoing bombardment, killing, and destruction which must be stopped fully and immediately in line with international resolutions…Any possible UN-sponsored ceasefire or cessation of hostilities agreement must ensure and end to all bombardments, killings, and forced displacements." the joint statement reads.
The Free Syrian Army was Damascus' major challenger at the beginning of the conflict when it managed to unite nearly all opposition factions considered by the West to be the so-called moderate opposition. The group is overtly supported by the United Kingdom, Qatar, Saudi Arabia, the United States, Turkey and France which sponsor the fighters with munition, arms and combat vehicles worth hundreds of US dollars.
The FSA split into several groups and shrank to some 60 units which are allied to Jabhat Fatah al Sham group previously known as al-Nusra Front, according to the Syrian intelligence.
Moscow and Washington are the key actors in mediation of the Syrian conflict tearing the country apart since March 2011, with government forces loyal to Syrian President Bashar Assad fighting numerous opposition factions and extremist groups.
The latest cessation of hostilities in Syria was brokered by the United States and Russia on September 9. After being implemented on September 12, the deal broke apart with repeated violations of the ceasefire from all sides.
