Earlier on Sunday, the Syrian army said that "the so-called worldwide alliance today noon targeted the jet over the area of al-Rasafa in the southern countryside of al-Raqqa while it was on a combat mission against the terrorist Daesh", using an Arabic acronym of ISIL, which is also known as ISIS.
The US has confirmed that in an incident Sunday evening, an American F/A-18E Super Hornet shot down a Syrian government Su-22 bomber south of Tabqa, accusing the Syrian jet of having dropped bombs on Kurdish fighters in the town of Ja'Din.
The coalition shot down a Syrian plane in self-defense after a regime SU-22 dropped bombs near SDF forces, the statement said.
Meanwhile, the Syrian army warned of the "dangerous repercussions" of the attack, stressing that such acts will not dissuade the Syrian army from carrying on with fighting the terrorist groups and restoring peace and security to all of Syria. About a month earlier, the United States fired cruise missiles at a Syrian military airfield after a regime-led chemical attack, although the strike was timed to avoid casualties.
This is the latest example of tension between the Russian-backed Syrian regime and USA -led coalition forces, who are partnering with Arab and Kurdish forces to destroy ISIS.
According to the statement, the plane was carrying out operations against Islamic State (IS, formerly ISIS/ISIL) in the countryside around Raqqa when it was targeted, leading to a crash and the loss of the pilot, who is now missing.
Coalition aircraft then stopped the pro-regime forces' initial advance with a "show of force", the coalition added.
Earlier this month, a U.S. F-15 shot down an Iranian drone in southern Syria after it fired on US -backed forces.
The Syrian jet had attacked fighters in the town of Ja'Din, which - accoring to the Coalition - sits two kilometers north of an established de-confliction area.
"The Coalition's mission is to defeat ISIS in Iraq and Syria", the USA task force in charge of operations in Syria and Iraq announced on Sunday.
