"I am grateful to the global community for the relative peace that lasted until April 2, but I have expressed my dissatisfaction that the format of the negotiations is flawed and it is not allowing to achieve real progress in the settlement process," Sahakyan said at a press briefing.
The OSCE Minsk Group, co-chaired by the United States, Russia and France, has been mediating the Nagorno-Karabakh conflict settlement since 1992. The group's ambassadors met in Vienna on Tuesday to discuss the recent outbreak of violence in the region.
"I repeat that any initiative, until it is adopted with the participation of the NKR, will not bring real results," Sahakyan stressed.
On Tuesday, Azerbaijan and Armenia agreed on an immediate ceasefire, but have since accused each other of multiple violations.
