A diplomatic solution to the conflict over the disputed Nagorno-Karabakh region is nowhere in sight, Armenian Prime Minister Nikol Pashinyan said on Wednesday, dealing a blow to efforts by world powers for a sustainable truce.
In a live video address on Facebook, Mr Pashinyan said the conflict "has not and will not have a diplomatic solution for a long time".
He urged all Armenians to “take up arms and defend the Motherland” and called on local mayors to organise volunteer units.
Armenia and Azerbaijan have been engaged in fierce fighting for almost a month over Karabakh, the region of Azerbaijan that broke away after the Soviet Union split up.
The biggest escalation since the end of the last conflict in 1994 has left hundreds dead, with world powers so far unable to persuade either side to stop fighting.
Azerbaijan and the Armenian separatists who live in and govern Karabakh have been locked in a bitter impasse over the fate of the mountain province since a war in the 1990s, which killed 30,000 people.
