Russia is closely following reports coming from the Nagorno-Karabakh conflict zone on Saturday morning, Russian Foreign Ministry spokesperson Maria Zakharova told Interfax.
"We are closely analyzing the incoming information," Zakharova told Interfax.
The situation in the conflict area dramatically deteriorated in the early hours of Saturday, and reports on numerous fatalities have been coming from there.
Azerbaijan and Armenia accused each other of starting the fighting, with both sides reporting casualties.
Azerbaijan said its armed forces came under fire first from large-calibre artillery and grenade-launchers. The Armenian government said Azerbaijan started the fighting with tanks, artillery, and helicopters.
The Nagorno-Karabakh military said Armenian anti-aircraft fire had shot down an Azeri helicopter, but Azerbaijan denied this, Reuters news agency reported.
Recognised by the UN as part of Azerbaijan, Nagorno-Karabakh controls most of the territory of the former Nagorno-Karabakh Autonomous Oblast and some of the surrounding area, giving it a border with Armenia to the west and Iran to the south.
