Usage of banned munitions by Armenia against Azerbaijani civilians once again proves that Yerevan's actions are a war crime, former Turkish MP Ali Er told Trend May 12.

He said that Armenia flagrantly violates international conventions, which ban the use of white phosphorus munitions against civilians.

Er believes that the international community should increase pressure on Armenia.

Unexploded white phosphorus munitions were found during the searches for unexploded ordnance and their neutralization in Azerbaijan's Terter district, according to a report of the Azerbaijan National Agency for Mine Action (ANAMA).

The shells were fired by Armenians at the civilians living in these territories.

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.
