NEW YORK, November 11. /TASS/. Russia is not to blame for the deadlock in the agreements on Syria, it was caused by Washington’s inability to disentangle extremists from moderate opposition, a spokesman for the Russian president said Friday.

"There was an agreement, achieved with great effort, which, unfortunately, was not implemented through no fault of Russia," Dmitry Peskov said. "The US and Washington’s partners have been unable to fulfill the key provision: to disentangle the so-called moderate opposition… from terrorist groups."

"Any political settlement is impossible as long as this problem remains unsolved, though, of course, experts continue their work," he went on.
