Explosions have rocked parts of Nagorno-Karabakh, a day after Azerbaijani forces used heavy artillery fire on Armenian positions in the separatist region that local officials said killed or wounded scores of people.

Azerbaijan has called the artillery fire an “anti-terrorist operation” and said it will continue until the separatist government of Nagorno-Karabakh dismantles itself and “illegal Armenian military formations” surrender.
