Russia says one of its helicopters crashed in Syria, killing the two pilots.

The Defense Ministry says the Mi-28N helicopter gunship crashed early Tuesday near Homs after completing its mission. It says there is no evidence that it came under fire.

The ministry says the bodies of the pilots have been recovered and taken to the Hemeimeem air base on Syria's coast.

Russia has been carrying out airstrikes since Sept. 30 in support of Syrian government forces. The air campaign has allowed Russia to test some of its latest weapons, including the Mi-28 helicopter.
