On Sunday, Azerbaijan and Armenia traded accusations of violating the second ceasefire which came into force, just hours earlier in the day, aimed at halting the fighting in the disputed region.
The accusations came despite the two warring countries welcoming the truce.
Following trilateral negotiations between Russia, Azerbaijan and Armenia that lasted for over two hours in Moscow, the first ceasefire was enforced in the region on October 11.
Renewed clashes between Azerbaijan and Armenia erupted on September 27, with intense battles raging in Nagorno-Karabakh, a disputed territory which is internationally recognized as part of Azerbaijan but mostly governed by the Republic of Artsakh, a de facto independent state with an Armenian ethnic majority.
The area experienced flare-ups of violence in the summer of 2014, April 2016 and in July tjis year.
Armenia and Azerbaijan went to war over the region in 1988-94, eventually declaring a ceasefire.
However, a settlement was never reached.
