Clashes erupted between Azerbaijani and Armenian forces due to the dispute over the Nagorno-Karabakh region.
An Azerbaijani helicopter was shot down in the clashes.
The Prime Minister of Armenia, Nikol Pashnyan, accused Azerbaijan of launching air and artillery attacks on his country’s forces.
However, Azerbaijan said it was responding to Armenian artillery shelling along the border.
There were reports of civilian casualties on both sides of the border.
And Armenia declared martial law in the disputed region.
The long-running conflict between the two countries has been renewed in recent months.
The Russian Foreign Ministry called for an immediate ceasefire and the start of talks to contain the conflict.
Armenia and Azerbaijan were part of the Soviet Union before its collapse in 1991.
The differences between the two countries centered on the Nogorno-Karabakh region for four decades. The area is considered by international law as part of Azerbaijan, but it is under Armenian control.
Clashes on the borders in July resulted in the death of 16 people, which led to the outbreak of demonstrations that were the largest in years in the Azerbaijani capital, “Baku”, calling for general mobilization and control of the disputed area.
What do the parties say:
The Armenian Ministry of Defense said that an attack on towns including Stepanakert, the capital of the disputed region, began at 8:10 minutes local time.
And it indicated, in an official statement, that the Armenian army shot down two Azeri helicopters and three drones, and destroyed three tanks.
“Our response will be proportional to the level of the attack, and we hold the political and military leadership in Azerbaijan fully responsible for the deterioration of the situation,” the statement said.
Ministry spokesman Shushan Stepanyan later said that a woman and child had been killed, and reports of other casualties were being verified.
And the authorities in the disputed area declared martial law.
Azerbaijan announced a counter-attack along the border to repel the Armenian armed forces’ military attacks and protect civilians.
The heavy shelling of several villages resulted in killing and wounding civilians and destroying parts of the infrastructure, according to the Ministry of Defense statement.
The statement added that an Azeri helicopter was shot down, but its crew survived, while 12 Armenian defense systems were destroyed. The statement denied any other losses reported by the Armenian statement.
The tension had developed into a military conflict in 2016, when clashes occurred between the two countries, which lasted for several days.
The OSCE has long been trying to mediate, with the participation of mediators from France, Russia and the United States, to settle the dispute. These countries formed a diplomatic group known as the Minsk Group of the European Organization, which is trying to build on a ceasefire agreement signed between the two countries in 1994 to reach a solution to the conflict.
