The armed forces of Azerbaijan resumed their attacks in three areas of the Nagorno-Karabakh conflict zone on Thursday, Armenian Defense Ministry Representative Artsrun Hovhannisyan told reporters.

“Throughout the day, heavy fighting continued along the entire line of contact, particularly in the southern zone, along the Aras River bank. We managed to drive back the enemy. Both sides are sustaining losses. The situation remains tense. The intensity of fire subsides at night,” he said.

At the talks, brokered by Russia and held in Moscow on October 9, Azerbaijan and Armenia agreed a ceasefire. It came into effect at 12.00 local time on Saturday, October 10 for humanitarian reasons, for the exchange of detainees and recovery of war dead.
