Armenia says it has shot down two Azerbaijani helicopters and destroyed three tanks in fighting around the disputed region of Nagorno-Karabakh.
The Defense Ministry of the breakaway region also claimed that they had destroyed four Azari helicopters, 15 drones and 10 tanks during the clashes on Sunday morning.
The Armenian Defense Ministry said the latest incident began with an Azerbaijani attack – and Azerbaijan said the Armenian side attacked first and they counter-attacked.
Both Armenia and Nagorno-Karabakh declared martial law and martial law. However, the Azerbaijani military says it has no need to do so because it is fully staffed.
The Armenian Defense Ministry has released video footage showing attacks on vehicles.
It said his army acted in response to attacks on civilian targets, including Stepankecart, the capital of Nagorno-Karabakh.
“Our response will be proportional and the military-political leadership of Azerbaijan will take full responsibility for the situation,” the statement said.
Both sides have received reports of civilian casualties.
Armenian Prime Minister Nikol Pasinian said on Twitter: “We stand by our army to protect our motherland from the Azeri invasion.”
Hikmet Hazayev, a senior adviser to Azerbaijani President Ilham Aliyev, has accused Armenian forces of carrying out “intentional and targeted” attacks.
Azerbaijan’s Defense Ministry says Armenia has attacked civilian settlements and military positions “on the line of contact”, a heavily mined no-man land, separating Armenian-backed forces from Azeri forces in the region.
It said some civilians had been killed “as a result of heavy shelling” in Armenia and that Azerbaijan had retaliated.
The ministry said the Azerbaijani army had “launched a counter-offensive with the entire front” to suppress the fighting activities of the Armenian armed forces and ensure the safety of civilians.
Turkey has demanded an end to “hostility” to Armenia, saying the region is at risk of “drowning”, while France has called on both sides to stop fighting and resume dialogue.
The two countries have been embroiled in a long-running feud over the Brexit region, with renewed tensions in recent months.
Shortly after the collapse of the Soviet Union in 1991, Nagrono-Karabakh declared independence from Azerbaijan.
Despite agreeing to a ceasefire in 1994, Azerbaijan and Armenia have often accused each other of aggression in the vicinity and on the separate Azeri-Armenian border.
