Azerbaijan has also violated the ceasefire with regard to civilian settlements, using military aviation against the town of Martuni, the Artsakh State Service of Emergency Situations reported.

"Moments ago, the adversary used military aviation in an attack on the city of Martuni, thus blatantly violating the ceasefire agreed for humanitarian purposes," the Service said in a statement.

To remind, earlier the US State Department announced that Armenia and Azerbaijan have agreed to a humanitarian ceasefire in Nagorno-Karabakh beginning on Monday 08:00 am local time.

This has been the third humanitarian ceasefire violated by Baku.
