At least 23 people were killed and over 100 sustained injuries on Sunday (local time) as heavy clashes broke out between Armenian and Azerbaij forces over the disputed separatist region of Nagorno-Karabakh.
Sixteen Armenian separatist fighters were killed and more than 100 wounded in the fighting, rebel officials said, Al Jazeera reported.
Both sides also reported casualties including at least one Armenian woman and child.
An Azerbaij family of five was reportedly killed in shelling launched by Armenian separatists.
Earlier in the day, heavy fighting between the forces of Azerbaijan and Armenia broke out in the disputed region of Nagorno-Karabakh region.
According to Al Jazeera, Armenia has declared martial law and ordered its military to mobilise after a major "flare-up in violence" with Azerbaijan broke out over the disputed region.
Heavy firing broke out between the two countries on Sunday and they both blamed each other for the escalation that led to casualties.
Armenia accused the neighbour Azerbaijan "of hurting civilian settlements" in Nagorno-Karabakh -- which is recognised as a part of Azerbaijan internationally but controlled by Armenian forces.
Azerbaijan launched what it described as a "counteroffensive," while the self-proclaimed Republic of Artsakh accused Azerbaij forces of opening fire against civilians and civilian infrastructure in its capital of Stepanakert.
