WASHINGTON (Sputnik) – UN Special Envoy for Syria Staffan de Mistura said Monday that warring parties had until September to solve the nation’s two key problems, namely defeating extremists and forming a unity government.
"I think it is some kind of artificial setting of deadlines for the things that must take place under any circumstances," Kislyak said.
He added that the Russian goal is to assist in destroying terrorists and developing political processes that would bring stability to Syria.
Syria has been mired in civil war since 2011, with government forces loyal to President Bashar Assad fighting a number of opposition factions and extremist groups.
On February 27, a US-Russia brokered ceasefire came into force in Syria. Terrorist groups such as Daesh, as well as Nusra Front, both outlawed in Russia and several other states, are not part of the deal.
