Three civilians were killed in Azerbaijan`s Terter district in the result of sabotages committed by the Armenian armed units on the frontline Apr. 2-5, head of the executive power of the district Mustagim Mammadov told on Apr. 6.

He said that those civilians died as a result of artillery shelling by the Armenians.

"Two of the victims were residents of the Terter district, and one was a resident of Ganja city," said Mammadov. "Another six people were hospitalized with injuries of various degrees."

On the night of April 2, 2016, all the frontier positions of Azerbaijan were subjected to heavy fire from the Armenian side, which used large-caliber weapons, mortars and grenade launchers.

The armed clashes resulted in deaths and injuries among the Azerbaijani population. Azerbaijan responded with a counter-attack, which led to liberation of several strategic heights and settlements.

Military operations were stopped on the line of contact between Azerbaijani and Armenian armies on Apr. 5 at 12:00 (UTC/GMT + 4 hours) with the consent of the sides, Azerbaijan`s Defense Ministry earlier said.

The conflict between the two South Caucasus countries began in 1988 when Armenia made territorial claims against Azerbaijan. As a result of the ensuing war, in 1992 Armenian armed forces occupied 20 percent of Azerbaijan, including the Nagorno-Karabakh region and seven surrounding districts. The 1994 ceasefire agreement was followed by peace negotiations. Armenia has not yet implemented four UN Security Council resolutions on withdrawal of its armed forces from the Nagorno-Karabakh and the surrounding districts.
