Azerbaijan says Armenian forces violating Karabakh ceasefire
"Armenian forces grossly violated another agreement," the defence ministry in Baku said in a statement, accusing them of firing artillery and mortars in various directions and of launching early morning attacks along the frontline.
Armenia's defence ministry had earlier accused Azerbaijani forces of violating the truce -- the second attempt in a week to quell fighting that has claimed hundreds of lives -- with shell and rocket fire.
Armenia and Azerbaijan accused each other of violating a new ceasefire over Nagorno-Karabakh on Sunday, as they tried for the second time in a week to bring a halt to fierce fighting over the disputed region.
The ex-Soviet neighbours agreed to a new truce from midnight on Sunday, as international mediators push for a stop to three weeks of heavy clashes over Nagorno-Karabakh, an ethnic Armenian region that broke from Azerbaijan's control in the 1990s.
A previous ceasefire agreed a week ago fell apart amid mutual accusations and continued fighting that has left hundreds dead and forced tens of thousands from their homes.
The new ceasefire deal was announced after one of the deadliest attacks on civilians so far on Saturday, when a missile strike hit a residential area of Azerbaijan's second city Ganja, killing 13 people including small children.
The two sides have described the agreement as a "humanitarian truce" to allow for the exchange of prisoners and bodies.
Its foreign ministry said Azerbaijan had also launched an attack in a southern area of the Karabakh frontline "demonstrating to the international community its treacherous nature, which we have been dealing with for decades".
Azerbaijan's defence ministry said Armenian forces had "grossly violated another agreement", accusing them of firing artillery and mortar shells in various directions and of launching early morning attacks along the frontline.
- 'We can't trust them' -
Azerbaijan and Armenia have been locked in a bitter conflict over Karabakh since Armenian separatists backed by Yerevan seized control of the mountainous province in a 1990s war that left 30,000 people dead.
The fighting that broke out three weeks ago has been the heaviest since a 1994 ceasefire and has threatened to draw in regional powers Turkey, which backs Azerbaijan, and Russia, which has a military alliance with Armenia.
An AFP journalist in Karabakh's main city Stepanakert said the night had been calm on Sunday and that, unlike during previous days, the sounds of explosions could not be heard coming from frontline areas.
But after the failure of other ceasefire attempts and decades of mistrust, there was little hope among city residents that a truce would take hold.
"Our country is ready to respect the ceasefire but the others will not... We can't trust them," Sveta Petrosyan, a 65-year-old with two sons at the front, told AFP outside her apartment.
Stepanakert has come under heavy artillery and rocket fire during the fighting and most of its residents have fled to Armenia.
It was shelled again late on Friday and a few hours later the missile strike hit Ganja in Azerbaijan, levelling a row of houses and leaving 13 dead and more than 45 people injured.
Azerbaijan's President Ilham Aliyev described the Ganja attack as a war crime and vowed his army would "take revenge on the battlefield".
- Houses turned to rubble -
An AFP team in Ganja saw rows of houses turned to rubble by the strike, which shattered walls and ripped roofs off buildings in the surrounding streets.
"We were sleeping and suddenly we heard the blast. The door, glass, everything shattered over us," said Durdana Mammadova, 69, who was standing on the street at daybreak because her house was destroyed.
The clashes over Karabakh that erupted on September 27 have left more than 700 dead, including scores of civilians on both sides.
The real death toll is probably much higher, as most of the deaths have been reported among Armenian separatist forces and Azerbaijan has not released any figures on its military casualties.
Both sides claim to have inflicted heavy losses. Azerbaijan says it has retaken significant territory in areas along the frontline. Armenian forces dispute these claims but have admitted to some setbacks.
It is unclear what set off the latest round of fighting but Armenia has accused Turkey of encouraging longtime ally Azerbaijan to launch an offensive to retake Nagorno-Karabakh. Ankara has also been accused of supplying Syrian fighters as mercenaries to bolster Baku's forces.
France, Russia and the United States have tried for decades to mediate a resolution to the dispute over Karabakh under the "Minsk Group", but negotiations have long been stalled.
