On 9 November 2020, a Russian Mil Mi-24 helicopter was shot down by the Azerbaijani Armed Forces during the Second Nagorno-Karabakh War. It was shot down near Yeraskh, in Armenia, a few kilometers away from Azerbaijan's Nakhchivan Autonomous Republic, as a result of fire from the ground from man-portable air-defense system. Two of the crew members died, while another was injured as a result of the attack. Azerbaijani authorities soon issued a statement of apology, saying that the shootdown happened by mistake and offered compensation.

The Battle of Shusha was the final and decisive battle of the Second Nagorno-Karabakh War, fought between the armed forces of Azerbaijan and the self-proclaimed Republic of Artsakh, militarily supported by Armenia, over the control of the city of Shusha. The battle is considered one of the bloodiest battles of the war.
