Volunteers line up to go to the front line in Yerevan, Armenia, after deadly clashes with Azerbaijan, Sunday, September 27.
Armenia declared martial law and total military mobilization after clashes with Azerbaijan over the Nagorno-Karabakh enclave, Armenian Prime Minister Nikol Pashinyan said Sunday.
The enclave has a majority Armenian population but is located entirely inside Azerbaijan.
Armenia accused neighboring Azerbaijan of attacks on civilian settlements in the disputed region.
The ministry also said its troops shot down two Azerbaijani military helicopters and three drones after Baku’s forces began bombing the breakaway enclave, including its capital, Stepanakert.
However, Azerbaijan's Defense Ministry said it had launched a military operation along the "contact line," between the two countries, “to suppress Armenia's combat activity and ensure the safety of the population."
The ministry confirmed the downing of only one Azerbaijani helicopter and said its crew had survived.
Peace efforts in the Nagorno Karabakh conflict, mediated by the "Minsk Group," collapsed in 2010.
Armenian separatists seized Nagorno-Karabakh from Azerbaijan in a bloody war in the 1990s that killed 30,000 people.
