Yeraskh

Yeraskh (, formerly, Arazdayan) is a village in the Ararat Province of Armenia. Yeraskh is the last Armenian village on the closed border with Azerbaijan's exclave of Nakhchivan, what used to be the main road and rail connections between Nakhchivan and Azerbaijan proper. The rail line also was the only direct connection between the former USSR and Iran.
Because of the hostilities between Armenia and Azerbaijan over Nagorno-Karabakh, the border is under severe blockade and no trains are allowed to pass. This line, the only direct connection between the former USSR and Iran, is now almost out of use.
On 9 November 2020, a Russian Mil Mi-24 attack helicopter (NATO reporting name "Hind") was shot down near Yeraskh by the Azerbaijani Armed Forces with a MANPADS during the 2020 Nagorno-Karabakh war. Two of the crew members died, while another was injured as a result of the attack.
