(INDEPENDENT) — Russia has said it will treat US warplanes operating in parts of Syria where its air forces are also present as “targets” amid a diplomatic row caused by the downing of a Syrian jet.

The country’s defence ministry said it would track US-led coalition aircraft with missile systems and military aircraft, but stopped short of saying it would shoot them down.

A hotline set up between Russia and the US to prevent mid-air collisions will also be suspended.
