"Six civilians died and 25 sustained various injuries as a result of an intense shelling from the heavy weaponry, mortars and artillery from the Armenian side at the beginning of April at the front line of Azerbaijani districts, including Agdam, Tartar, Goranboy, Fuzuli and Aghjabadi districts," Qaralov was quoted as saying by the Trend news agency.
He added that 641 residential buildings and 22 social sites were damaged by the artillery shelling.
Armenia and Azerbaijan have been engaged in a dispute over Nagorno-Karabakh since 1988, when the autonomous region left the Azerbaijan Soviet Socialist Republic and proclaimed independence after the Soviet Union collapsed in 1991. The secession triggered a war that lasted until a Russia-brokered ceasefire was signed in 1994.
