Russia's defense ministry says it will treat US-led coalition planes in Syria that venture west of the Euphrates River as targets after the US military shot down a Syrian Air Force jet on Sunday, reports the AP. Moscow also suspended a military hotline the two nations have used to coordinate air missions over Syria, reports the New York Times. Russia condemned the US downing of the Syrian government fighter jet as a "military aggression" and demanded a fuller explanation. The US has said the Syrian jet dropped bombs near its partner forces, but Syria said its jet was attacking ISIS militants.
“All flying objects, including planes and drones of the international coalition, detected west of the Euphrates, will be followed by Russian air defense systems as targets,” the Russian Defense Ministry said in a statement. The downing of the warplane—the first time in the conflict that the US has shot down a Syrian jet—came as Iran fired several ballistic missiles at ISIS positions in eastern Syria in retaliation for two attacks by the extremists in Tehran earlier this month that killed 17 people. Areas of northern Syria west of the Euphrates were controlled by ISIS before Syrian government forces captured most of them in recent months. (Read more Russia stories.)
