Russia said Monday that it will no longer use a "de-confliction" channel intended to help it steer clear of conflict with the U.S. as the nations battle terrorism in Syria. Russia's announcement came a day after a U.S. aircraft on Sunday downed a Syrian government fighter jet, prompting Russia, which supports Syrian President Bashar al-Assad's forces, to announce that any U.S.-led coalition planes flying west of the Euphrates River will be considered "air targets." A top Russian official described the downing of the plane as "an act of aggression that assists terrorists." The Syrian army claimed it was carrying out a mission against the Islamic State; the U.S. said the Syrian plane dropped bombs near U.S.-backed Syrian Democratic Forces.
