Later the US Central Command issued a statement saying the Syrian plane was downed "in collective self-defense of Coalition-partnered forces", identified as fighters of the Syrian Democratic Forces (SDF) near Tabqah.
A top Russian diplomat on Monday condemned the United States for shooting down a Syrian Air Force fighter jet the previous day as an act of "aggression", while US -backed opposition forces on the ground warned Syrian government troops to stop their attacks or face retaliation.
Earlier, the US military confirmed that a US Navy F/A-18 Super Hornet had shot down a Syrian SU-22 on Sunday.
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. "If the regime continues attacking our positions in Raqqa province, we will be forced to retaliate", SDF spokesman Talal Silo said.The Syrian government this month marched into Raqqa province from the west but had avoided conflict with the USA -backed SDF until the latest incident.
Iran and Syria are determined to establish a "Shiite" supply corridor between Iran and Syria that would run directly through territory on the Iraq-Syria border that is now controlled by coalition forces based out of the At Tanf garrison.
A top Russian diplomat has condemned the United States for shooting down a Syrian Air Force fighter jet the previous day as an act of "aggression". The coalition also said that Russian officers had been contacted on a special "de-confliction" hotline in an effort to halt the assault.
The Syrian air force had targeted coalition-backed troops fighting ISIS around their capital of Raqqa. On June 8, US officials reported that a drone likely connected to Iranian-supported Hezbollah forces fired on USA -backed troops and was shot down by an American fighter jet. The incident comes at a time when the United States led coalition and its fighters present on the ground are fighting against the Islamic State (ISIS) in its Syrian stronghold of Raqqa. That means the U.S. must now account for a more antagonistic stance by Syrian and Russian Federation forces. Washington is leading an alliance in the fight against Islamic State in Syria.
The newly elected Liberal government withdrew the CF-18s the following year, but kept the other planes in the region to continue supporting fighter jets from the US and other allied countries. Hundreds of USA special operations forces are working alongside Syrian rebels fighting the Islamic State, while US warplanes and a Marine Corps artillery unit provide firepower for the advancing forces on a daily basis. But the USA scrambled aircraft to roar over the battlefield in "a show of force" that halted the pro-government forces' advance. (The corps uses the term takfiri, or apostate, to describe Islamic State militants as well as a number of other Sunni Muslim extremist groups).
The Russian Defense Ministry also said it will stop communications with US military aimed at preventing mid-air accidents.
