Russia says the Syria cease-fire can only resume if attacks against government forces stop.
Kremlin spokesman Dmitry Peskov said on September 20 that hope for a renewal of the cease-fire was for now "very weak."
"The conditions are very simple," Peskov added. "The shooting needs to stop and the terrorists need to stop attacking Syrian troops."
"And of course it wouldn't hurt if our American colleagues didn't accidentally bomb the Syrians," he also said, referring to a U.S.-led coalition strike last week that killed at least 62 Syrian soldiers.
Peskov’s comments come as the International Syria Support Group, comprised of countries supporting opposing sides in the conflict, gathered in New York.
On his way into the meeting, German Foreign Minister Frank-Walter Steinmeier said world powers must look to see if there is a way back to negotiations on a truce "or if this has already become hopeless."
On September 19, Syria's military declared a one-week truce brokered by the United States and Russia over, with Washington and Moscow blaming each other for not doing enough to fulfill the deal.
