"We are appealing to the government of the Russian Federation with a request to interfere in order to ease burden of civilian population living in a number of districts not under control of the Syrian government. This [is necessary] for opening safe humanitarian corridors and an urgent delivery of basic humanitarian aid to these people, including food and medicines," the Astana-2 members said in a joint appeal obtained by RIA Novosti.
During the first round of Astana talks in May, Syrian opposition groups signed off on a final document calling for the withdrawal of all foreign mercenaries from Syria and stressing the necessity to form a unified front to counter terrorism.
Syria has been in a state of civil war since 2011. Forces loyal to the President Bashar Assad have been fighting opposition and numerous extremist militant groups, including Islamic State and Nusra Front.
