Russia's Defense Ministry said on Monday it would view as targets any flying objects over Syria in the areas of the country where its air forces operate, Russian news agencies reported.
The statement followed after a U.S. warplane shot down a Syrian army jet on Sunday in the southern Raqqa countryside, with Washington saying the jet had dropped bombs near U.S.-backed forces and Damascus saying the plane was downed while flying a mission against Islamic State militants.

The Defense Ministry also said that it was suspending its interaction with the United States on preventing air incidents over Syria from June 19, the agencies reported.
The U.S. did not use its communication channel with Russia ahead of the downing of the Syrian government warplane, the ministry was quoted as saying.
