According to a news release of the US Department of Defense, the coalition’s aviation performed combat missions in Dier ez-Zor on Saturday.

The Russian Defense Ministry said that the aircraft which carried out the bombings had entered Syrian airspace from the territory of Iraq.

Four strikes against Syrian positions was performed by two F-16 jet fighters and two A-10 support aircraft, it added.

“If the airstrike was caused by the wrong coordinates of targets than it’s a direct consequence of the stubborn unwillingness of the American side to coordinate with Russia in its actions against terrorist groups in Syria,” Konashenkov stressed.
