The struggle between Armenia and Azerbaijan in Nagorno-Karabakh must stop immediately. Kremlin spokesman Dmitri Peskov said this Monday.
The Kremlin urged Azerbaijan and Armenia to stop all military activities that further inflame tensions over Nagorno-Karabakh territory.
The fighting is cause for serious concern in Moscow, Peskov said.
Moscow is closely following the situation, and Peskov added that the conflict must be resolved through diplomacy.
Armenian and Azerbaijani forces fought for the breakaway region for the second day on Monday, with both sides accusing each other of using heavy artillery.
