Armenia and Azerbaijan accused each other on Sunday of violating a new humanitarian ceasefire in fighting over the mountain enclave of Nagorno-Karabakh, hours after it was agreed.
The truce agreed on Saturday came into force at midnight (2000 GMT) after a week-old Russian-brokered ceasefire failed to halt the worst fighting in the South Caucasus since the 1990s. At least 750 people have been killed since fighting began on Sept. 27.
At 1010 GMT, the Azeri defence ministry said the Aghdam region, adjacent Nagorno-Karabakh, was under Armenian shelling. It said overnight Armenian military units opened fire from large-caliber weapons along the border, which Armenia denied.
Armenia said the Azeri army had fired twice during the night and used artillery and accused Baku of rejecting its request to withdraw the wounded soldiers from the battlefield.
Nagorno-Karabakh says 673 of its military personnel have been killed, and 36 civilians.
