"There are hundreds of militant groups wielding across Syria. Country's territory is bombed by anyone who feels like doing it. Syria's return to peace has become almost an impossible task," Churkin said speaking at the UN Security Council.
"Constantly new conditions [for cessation of hostilities in Syria] were put forward. We have always sought compromise, but ultimately this leads to the fact that the rebels and the armed groups carry out new attacks, then there was a requirement stating that the Syrian government had to unilaterally stop flights by its armed forces. And initially that was for three days and we did agree to that. Unilateral steps are something that we will not agree to any more."
He also stressed the necessity to resume the political process settlement in Syria.
"We need to renew the political process. Quite frankly speaking it is not clear to us why decisive steps in this area have not been taken since May," Churkin told the UN Special Envoy for Syria Staffan de Mistura speaking at the UN Security Council.
France, the UK and the US called an emergency UN Security Council meeting over the situation in Syria's Aleppo.
