Armenia said on Tuesday that at least 49 of their soldiers had been killed in conflicts with Azerbaijan along the border of two countries, reports swissinfo.
This bloodshed occurred after a sharp rising in hostilities which prompted Russia and the United States to call for restraint, claimed Armenian government.
The escalation of decades-old hostilities between the south Caucasus countries has fuelled fears of breaking out of a second fully-fledged war in the post-Soviet world amid Russia's invasion of Ukraine.
Armenia said several towns near the border with Azerbaijan, including Jermuk, Goris and Kapan, were being shelled in the early hours of Tuesday, and that it had responded to what it called a "large-scale provocation" by the Azerbaijan.
Conversely, Baku said it was attacked by Armenia.
Armenian Prime Minister Nikol Pashinyan accused Azerbaijan of attacking Armenian towns because it did not want to negotiate over the status of Nagorno-Karabakh, an enclave which is inside Azerbaijan but mainly populated by ethnic Armenians.
"The intensity of hostilities has decreased but attacks on one or two fronts from Azerbaijan continue," Pashinyan said in a speech to parliament.
Azerbaijan, which accused Armenia of carrying out spying activities along the border and moving weapons, said its military positions came under attack by Armenia. Azeri media reported that a ceasefire agreement had been broken almost immediately after being enforced early on Tuesday.
