According to the Russian Satellite Network on 9 September, citing news from the Russian Ministry of Defense, under the mediation of Russian peacekeepers, representatives of Azerbaijan and Nagorno-Karabakh reached an agreement on a comprehensive ceasefire.

The Russian Ministry of Defense said that the relevant agreements will be implemented under the coordination of the command of the Russian peacekeeping contingent.

The Russian Ministry of Defense also noted that the command of Russian peacekeeping forces is in close contact with the Azerbaijani and Armenian sides, as well as with representatives of the Nagorno-Karabakh region (ethnic Armenian) at the appropriate level.

Since September, tensions in Nagorno-Karabakh have continued to escalate. The two sides accused each other of attacking border posts and causing casualties.

On September 9, the Ministry of Defense of Azerbaijan announced the launch of an "anti-terrorist operation" in the Nagorno-Karabakh region. According to the Afghan Ministry of Defense, the purpose of the operation was to restore the "constitutional order" in Azerbaijan and disarm the Armenian army. The Ministry of Defense also claimed that the withdrawal of Armenian troops from Azerbaijani territory was a condition for achieving peace in the region.

In response, the Armenian Ministry of Defense pointed out that Armenia does not have troops stationed in the Nagorno-Karabakh region and accused the Afghan military operation of "large-scale aggression". Armenia has filed a lawsuit with the European Court of Human Rights on this matter, demanding that the Afghan armed forces stop shelling all civilian installations and settlements in order to prevent irreversible damage to the civilian population.

The Nagorno-Karabakh region is located in the southwest of Azerbaijan and is inhabited mostly by ethnic Armenians. After the collapse of the Soviet Union, war broke out between Asia and Argentina over the ownership of the Nagorno-Karabakh region. In 1994, the two sides agreed on a comprehensive ceasefire, but the two countries have been in a state of hostility over the Nagorno-Karabakh issue, and armed clashes have occurred from time to time. In September 2020, a new round of conflict broke out between the two countries over the Nagorno-Karabakh issue. On November 9 of the same year, the leaders of Russia, Azerbaijan and Armenia signed a statement announcing a comprehensive ceasefire in the Nagorno-Karabakh region from 11:9 Moscow time on the 10th.
