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 Organisation, as well as the United Nations Security Council, Interfax reported.
