Planes, personnel and military vehicles are heading to Nagorno-Karabakh for a peacekeeping mission.
The Russian Ministry of Defence has released footage of Russian peacekeepers and military vehicles at Erebuni airport in Armenia, where Moscow has a military base.
According to the ministry, 20 planes and 400 personnel, as well as military vehicles, have arrived.
The first set of Russian troops were deployed to Nagorno-Karabakh on Tuesday under a deal that halted six weeks of fighting between Azeri and ethnic-Armenian forces.
The agreement ended military action and restored relative calm to the breakaway territory, internationally recognised as part of Azerbaijan but populated and, until recently, fully controlled by ethnic Armenians.
It came after Armenia lost control of a strategic city in Nagorno-Karabakh, known as Shusha to Azerbaijan and Shushi to Armenians, and after the accidental downing of a Russian plane by Azeri forces.

â€œIf the fighting continued, there was a very high probability that Stepanakert, Martuni, Askeran would have fallen. Subsequently, thousands of our soldiers could be surrounded, that is, a collapse would have happened. We had to sign that agreement,â€ he noted,â€ Armenian Prime Minister Nikol Pashinyan said on Wednesday during a live broadcast on his Facebook page.
