"We are asking our colleagues to tell us where the moderate opposition is — it was our first question… There are many things like this that must be resolved with our American colleagues," Shoigu told the Rossiya-1 broadcaster.
Russia’s other proposition to the United States included determining where the Russian aviation should not conduct airstrikes, as well as gathering information from Washington on the exact location of terrorists in the war-torn country, Shoigu added.
Syria has been mired in civil war since 2011, with government forces loyal to President Bashar Assad fighting numerous 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 Jabhat Fatah al Sham (previously known as the Nusra Front), both outlawed in Russia and a range of other states, are not part of the deal.
