RUSSIA’S Defence Ministry warned yesterday, following the US downing of a Syrian Su-22 fighter-bomber, that it will treat US coalition planes west of the Euphrates river as targets.

Moscow called on the US military to come clean on why it shot down the Syrian plane over Raqqa province, where the Syrians say it was attacking Isis positions — the US claims the jet had bombed close to US-backed Syrian Democratic Forces (SDF) positions.

Moscow has suspended co-ordination with the US in Syria over “deconfliction” zones after Washington designated zones unilaterally.
