The aggravation of the situation on the border between Armenia and Azerbaijan is alarming, the Nagorno-Karabakh conflict must be resolved by peaceful means, said Deputy Director of the Information and Press Department of the Russian Foreign Ministry Alexey Zaitsev.

According to him, Russia is very concerned about the recent aggravation of the situation on the border of friendly Armenia and Azerbaijan, RIA Novosti reported.

"We are convinced that the long-term Nagorno-Karabakh conflict, like any other disagreements in the international arena, must be resolved exclusively by peaceful means, through diplomatic negotiations," he noted.

Zaitsev noted that the Russian leadership made all the necessary efforts to prevent further escalation, including via operational interaction with key partners in the region. 

In particular, Zaitsev mentioned the recent phone talks between Russian Foreign Minister Sergey Lavrov and his Azerbaijani and Armenian counterparts, as well as the discussion with the Turkish side of the current situation in the South Caucasus and especially in the Nagorno-Karabakh settlement.

"Mutually stating their serious concern about the dangerous development of events in the region, Russia and Turkey proceed from the lack of alternative political and diplomatic solutions to existing issues based on the principles of international law in the interests of the peoples of Azerbaijan and Armenia," he noted.
