Australia  suspended air strikes into Syria following the U.S. downing of a Syrian military jet and Russia's subsequent threat against U.S.-led coalition aircraft, Reuters reported quoting Australia's Department of Defence.

Russia said on Monday it would treat U.S.-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. 

"As a precautionary measure, Australian Defence Force (ADF) strike operations into Syria have temporarily ceased," Australia's Department of Defence said in a statement. 

On Sunday, a US jet shot down a Syrian Su-22 fighter-bomber near the city of Tabqa.
