Iranian Parliament Speaker Ali Larijani has expressed his concerns over fresh fighting between Azerbaijan and Armenia along their borders.
"The latest clashes between Azerbaijan and Armenia have caused concerns in the region," ISNA news agency quoted Ali Larijani as saying.
He called upon the governments and parliaments of Azerbaijan and Armenia to resolve the dispute through negotiations.
On the night of April 2, all the frontier positions of Azerbaijan were subjected to heavy fire from the Armenian side, which used large-caliber weapons, mortars, grenade launchers and guns.
Later on the same day, Azerbaijani defense ministry announced that the country's armed forces launched counter-attack operations against Armenia that led to the liberation of several strategic heights and settlements.
However, later on taking into account the international organizations' appeals, Azerbaijan announced unilateral suspension of the counter-attacks and response measures in the territories occupied by Armenia.
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.
