An American warplane has shot down a Syrian military aircraft that dropped bombs near US-led coalition fighters in western Raqqa, the USA military says.
The forces, who were operating near Tabqa at the time, were later identified as fighters form the Syrian Democratic Forces (SDF).
The U.S. military issued a statement saying the action was justified in light of a previous incident when Syrian warplanes dropped bombs in the vicinity of US-backed fighters and injured a number of troops. Following the pro-Syrian forces attack, the coalition called its Russian counterparts "to de-escalate the situation and stop the firing", according to the statement.
A Syrian warplane was shot down near Raqqa by the United States-led coalition after the regime wounded Syrian Democratic Force fighters in an earlier attack.
The U.S. military says it has shot down a Syrian Air Force fighter jet that bombed local forces aligned with the Americans in the fight against Islamic State militants. As the attack unfolded, the USA military used a deconfliction channel to communicate with the Syrian government to stop the skirmish, according to the Pentagon statement.
"The Coalition's mission is to defeat ISIS in Iraq and Syria".
USA forces tangled earlier this month with Syria-allied aircraft in the region.
'This comes at a time when the Syrian army and its allies were making clear advances in fighting the Daesh (Islamic State) terrorist group'.
