YEREVAN (Sputnik) — Earlier in the day, Armenia and Azerbaijan noted a sharp escalation of the situation in the mountainous Nagorno-Karabakh area, with both sides accusing each other of violating the ceasefire that has been in place since 1994.
"The president of Armenia has on Saturday summoned a meeting of the National Security Council. The agenda includes Azerbaijan's aggressive actions on the Karabakh-Azerbaijani contact line and related issues," the press statement said.
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 violating the truce.
