Armenia and Azerbaijan have negotiated a ceasefire to end a flare-up of fighting that has killed 155 soldiers from both sides, a senior Armenian official said.

Yerevan has called on big powers to pay further attention to the growingly serious situation.

New clashes have erupted between Azerbaijan and Armenia, in a resumption of decades-old hostilities between Baku and Yerevan over the contested Nagorno-Karabakh region.

A ceasefire agreed between Azerbaijan and Armenia fell apart minutes later amid a flare-up in hostilities between the two estranged neighbors.

Armenia's Industry Minister Vahagn Khachaturyan has been elected as the country's new president by the parliament.

President Sarkissian has announced his resignation, citing insufficient constitutional authorization to influence events.

Both sides accuse one another of initiating "provocations" that sparked the exchange of fire.
