As the leader of the international coalition against Islamic State, the US failed to ensure the implementation by its Turkish allies of the Syria air safety agreement, which was signed between Moscow and Washington, the Russian Foreign Ministry says. It reported by RT.

"Despite the fact, that the defense ministries of the two countries (the US and Russia) signed a memorandum on ensuring the safety of military aviation flights in Syrian airspace, Washington - which took the responsibility for the actions of the entire coalition it leads - hasn’t ensured compliance with the relevant provisions of the document by its ally Turkey,” the Foreign Ministry said in a statement on Monday.

Russia and the US signed an agreement regulating the operations of the two countries' air forces over Syria on October 20.

The memorandum established 24/7 communication channels between Russian and American military commanders, in order to prevent incidents and provide for the smooth operation of the two nations' aircraft, and for mutual aid in critical situations.

As part of the deal, the American side pledged to convey the details of the deal to their anti-Islamic State coalition partners, to follow the rules it sets.
