Moscow stands for the strict observance of the agreements on permanent ceasefire from 1994 and 1995 on the Armenia-Azerbaijan Nagorno-Karabakh conflict's settlement, Russia's Foreign Minister Sergey Lavrov said Apr. 22 in Yerevan.

He made the remarks opening the negotiations with Armenian Foreign Minister Edward Nalbandian, RIA Novosti agency reported.

"We, personally Russia's President Vladimir Putin, made efforts to stop the outbreak of violence," said Lavrov.

It is necessary to complete the agreements under the auspices of the OSCE with regards to the confidence-building measures, to defuse tension, snipers, according to Lavrov.

"As for the political settlement, we are ready to do everything possible," noted Lavrov adding that everything possible should be done to avoid violence and incidents.

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. Ignoring the agreement, the Armenian side again started violating the ceasefire.

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.
