MOSCOW (Sputnik) — Russian Foreign Minister Sergei Lavrov said Monday that he and Defense Minister Sergei Shoigu had contacted their counterparts in Baku and Yerevan to express concerns over the conflict unfolding in Nagorno-Karabakh.
"Minister Shoigu and I contacted our colleagues in Baku and Yerevan — the foreign and defense ministers of both countries. We expressed our grave concern and reiterated the Russian president's call to immediately stop violating the ceasefire regime," Lavrov told reporters.
"We hope that our calls were heard," he added.
The conflict in Nagorno-Karabakh began in 1988, when the Armenian-dominated autonomous region sought to secede from the Azerbaijan Soviet Socialist Republic, before proclaiming independence after the Soviet Union's collapse in 1991. In September 2015, the conflict escalated, with the sides blaming each other for breaching the truce.
