Sharjah24 – AFP: New tensions erupted over Nagorno-Karabakh on Wednesday as three soldiers were killed and Azerbaijan said it had taken control of several strategic heights in the disputed region.
The escalation drew immediate international reaction, with Russia accusing Baku of violating the brittle ceasefire and the European Union urging an "immediate cessation of hostilities".
Arch enemies Armenia and Azerbaijan fought two wars -- in 2020 and in the 1990s -- over Azerbaijan's Armenian-populated region of Nagorno-Karabakh.
Armenia ceded swathes of territory it had controlled for decades, and Russia deployed some 2,000 peacekeepers to oversee the fragile truce, but tensions persist despite a ceasefire agreement.
On Wednesday, new tensions erupted as Azerbaijan said it had lost a soldier and the Karabakh army said two of its troops had been killed and more than a dozen injured.
The Azerbaijani defence ministry said Karabakh troops targeted its army positions in the district of Lachin, which is under the supervision of the Russian peacekeeping force, killing an Azerbaijani conscript.
The Azerbaijani army later said it conducted an operation dubbed "Revenge" in response and took control of several strategic heights in Karabakh.
The army of the breakaway statelet for its part accused Azerbaijan of violating a ceasefire and killing two soldiers and wounding another 14.
Karabakh declared a "partial mobilisation", the army said in a statement.
Armenia called on the international community to help stop Azerbaijan's "aggressive actions" after the flare-up.
"Azerbaijan continues its policy of terror against the population of Nagorno-Karabakh," the foreign ministry said.
Armenia accused Azerbaijan of seeking to make unilateral changes over the Lachin corridor that links Armenia and Karabakh.
