Armenia has appealed to the International Court of Justice (ICJ) over Azerbaijan's installation of a checkpoint on the only road linking Armenia to Nagorno-Karabakh, Russian media reported on Wednesday.
The checkpoint on the road, known as the Lachin corridor, was set up on Sunday. The two countries have fought two wars since the collapse of the Soviet Union over Nagorno-Karabakh, an enclave that is internationally recognised as part of Azerbaijan but populated mainly by ethnic Armenians.
