"The United States took upon itself an obligation to do this within a week. Unfortunately, they have not done this. This is all that can be stated based on the bilateral obligations recorded in the document, not based on some excuses," Peskov said.
The United States disguises its inability to meet obligations on Syria by groundlessly accusing Russia of "all mortal sins," Dmitry Peskov said.
US Department of State spokesman John Kirby said Wednesday that the United States would disengage cooperation with Russia over the Syrian crisis unless Moscow took immediate steps to stop operations of the Syrian army in the city of Aleppo and reinstated a ceasefire.
"So far this is the main stumbling block. We certainly would not want to see a situation where failure to meet these obligations taken on by our colleagues from Washington would be camouflaged with absolutely unfounded accusations toward Russia of all mortal sins," Peskov told reporters.
"This is at least inappropriate, untrue, and most importantly does not help us move forward together in the fight against terrorists," he underscored.
There is no ground to treat seriously the reports of the United States considering airstrikes against the positions of the Syrian army, as they have no specific source, Kremlin spokesman said.
Earlier in the day, media reports claimed that US officials discussed increasing support for the Syrian opposition and even a US airstrike on a Syrian army air base as alternatives.
"These are reports without a specific source, hanging in mid-aid, so there is currently no reason to treat them seriously," Peskov told reporters.
