Renewed border clashes between Azerbaijan, Armenia

Clashes erupted between Azerbaijani and Armenian troops, Russian news agencies reported early on Tuesday, in a resumption of decades-old hostilities linked to the disputed territory of Nagorno-Karabakh.

Azerbaijan, which re-established full control over the territory in a six-week conflict in 2020, acknowledged casualties among its forces. Armenia made no mention of losses, but said clashes persisted overnight.

The Yerevan government said it would invoke a cooperation agreement with Russia and appeal to a Russia-led security bloc, the Collective Security Treaty Organization, as well as the United Nations Security Council, Interfax reported.

In addition to Russian President Vladimir Putin, Armenian Prime Minister Nikol Pashinyan has called French President Emmanuel Macron and United States Secretary of State Antony Blinken to discuss the situation. Blinken urged an immediate end to hostilities for which each side has blamed the other.

Azerbaijani statements said Armenian forces had been engaged in intelligence activity on its border, moved weapons into the area and on Monday night had conducted mining operations.

Conflict first broke out in the late 1980s when both sides were under Soviet rule and Armenian forces captured swaths of territory near Nagorno-Karabkah - long recognized internationally as Azerbaijan's territory, but with a large Armenian population.

Azerbaijan regained those territories in the 2020 fighting, which ended with a Russian-brokered truce and thousands of residents returning to homes from which they had fled. The leaders of both countries have since met several times to hammer out a treaty intended to establish a lasting peace.
