The Russian Ministry of Defence aired footage on Monday showing a base where Russian peacekeepers are staying in Nagorno-Karabakh.

The footage showed their canteen, gym and sleeping areas.

Russian peacekeepers entered Nagorno-Karabakh as part of a ceasefire brokered by Moscow, after a new round of fighting broke out in September.

Nagorno-Karabakh lies within Azerbaijan but was under the control of ethnic Armenian forces backed by Armenia since a separatist war there ended in 1994.

That war left Nagorno-Karabakh itself and substantial surrounding territory in Armenian hands.

In 44 days of fighting that began in late September and left more than 5,600 people killed on both sides, the Azerbaijani army forged deep into Nagorno-Karabakh, forcing Armenia to accept last month's peace deal.

Russia deployed nearly 2,000 peacekeepers for at least five years to monitor the agreement and facilitate the return of refugees.
