Izvestia cited unnamed military officials as saying the missiles arrived Friday, but did not say how many. The Defense Ministry declined comment on the report.
S-400s, Russia’s most advanced surface-to-air missiles, have a range of 120-400 kilometers (75-250 miles).
The report comes amid rising tension between the U.S. and Russia over Washington’s plans for a missile-shield system in Europe, which Russia contends threatens its own defenses.
S-400s are already deployed around Moscow and are planned to be placed in the Pacific Far East this year.
