Azerbaijan and Armenia accused each other of swiftly violating the terms of a ceasefire in Nagorno-Karabakh on Saturday, raising questions about how meaningful the truce, brokered by Russia, would turn out to be.
The ceasefire, clinched after marathon talks in Moscow advocated by President Vladimir Putin, was meant to halt fighting to allow ethnic Armenian forces in Nagorno-Karabakh and Azeri forces to swap prisoners and war dead.
But within minutes of the truce taking effect from midday, both sides accused each other of breaking it.
The Armenian defense ministry accused Azerbaijan of shelling a settlement inside Armenia, while ethnic Armenian forces in Karabakh alleged that Azeri forces had launched a new offensive five minutes after the truce took hold.
Azerbaijan said enemy forces in Karabakh were shelling Azeri territory. Both sides have consistently denied each others’ assertions about military activity.
In a statement which suggested the ceasefire was not completely dead however, Azeri President Ilham Aliyev said the warring parties were now engaged in trying to find a political settlement.
Speaking after 11 hours of Moscow-mediated talks between Armenia and Azerbaijan, Russian Foreign Minister Sergei Lavrov said earlier that the warring sides had agreed to a ceasefire from "12 hours 00 minutes on October 10 on humanitarian grounds."
Russia's top diplomat also said that Armenia and Azerbaijan agreed to start negotiating a peaceful solution to the territorial dispute.
"Azerbaijan and Armenia begin substantive negotiations with the purpose of achieving a peaceful settlement as soon as possible," Lavrov told reporters, adding that such talks would be mediated by France, Russia and the US.
Renewed fighting over Karabakh -- an ethnic Armenian region of Azerbaijan that broke from Baku's control in a devastating war in the early 1990s -- has claimed some 400 lives and forced thousands of people from their homes.
The heavy clashes erupted late last month, with both sides blaming the other for the biggest outbreak in violence since a 1994 ceasefire left the status of Karabakh in limbo.
Azerbaijani President Ilham Aliyev, who has repeatedly vowed to use his military to retake the breakaway province, said earlier that the talks represented a historic opportunity for Armenia.
"We are giving Armenia a chance to settle the conflict peacefully," he said. "This is their last chance."
Armenia's Prime Minister Nikol Pashinyan said his country was "ready for the resumption of the peace process" led by international brokers.
Heavy clashes continued into Friday, Armenian and Azerbaijani defense officials said, with further civilian deaths reported, even after Russian President Vladimir Putin announced the Moscow meeting and appealed for a ceasefire on humanitarian grounds.
Shelling started again in Stepanakert, the provincial capital of Karabakh, where an AFP journalist heard several explosions and saw the remains of a rocket in a crater next to a cemetery for dead soldiers.
A spokesman for the Armenian defense ministry told reporters on Friday that fighting continued despite the negotiations in Moscow.
