Russian diplomat condemns United States for downing Syrian fighter jet

Dunford noted that the hotline, which has been vital inprotecting both USA and Russian forces operating in Syria, remained in use "over the last few hours".The Syrian jet was shot down yesterday evening afterregime forces engaged the US-backed Syrian Democratic Forces (SDF), an alliance of Arab and Kurdish fighters battling IS, near Raqa.

Marine Gen. Joseph Dunford, the chairman of the Joint Chiefs of Staff, said he was aware of reports that Moscow had threatened to "target" U.S. military planes flying west of the Euphrates River in Syria on the day after a U.S. Navy F/A-18E Super Hornet shot down a Syrian warplane.

The shootdown incident and Russia's response further complicate Syria's six-year war and come as the US-led coalition and allied fighters battle to oust the Islamic State group from its Syrian bastion Raqa.

The White House says it retains the right to self-defence in Syria.

Russian Federation said on Monday it would treat US -led coalition aircraft flying west of the River Euphrates in Syria as potential targets and track them with missile systems and military aircraft, but stopped short of saying it would shoot them down.

The jet was downed on Sunday evening after regime forces targeted the US-backed Syrian Democratic Forces, an alliance of Arab and Kurdish fighters battling IS.

The Russian military alleged that in Sunday's incident, "the command of the coalition forces did not use the established communication channel for preventing incidents in Syrian airspace".

Russian Deputy Foreign Minister Sergei Ryabkov said of the USA military action in Syria, "What is this, if not an act of aggression?"

The coalition said Syrian troops attacked SDF fighters near Tabqa, south of Raqa, wounding several and chasing them out of the town.

Joint Chiefs of Staff Chairman Gen. Joe Dunford says that the U.S. is looking to reestablish its hotline with the Russian military as relates to deconfliction efforts in Syria.

Russian Deputy Foreign Minister Sergei Ryabkov, in comments to Russian news agencies, compared the downing to "helping the terrorists that the U.S.is fighting against".

Earlier this month, the coalition fired on pro-regime ground forces who approached the garrison and shot down a pro-regime armed drone.
