Russian President Vladimir Putin and his French counterpart Emanuel Macron have expressed serious concern over the ongoing full-scale hostilities around the Nagorno-Karabakh region.
"[The parties] have thoroughly discussed the dramatic escalation of the situation in the Nagorno-Karabakh conflict zone", the Kremlin press service said in a statement on Wednesday.
Putin and Macron discussed future steps the Minsk OSCE group could take to de-escalate the conflict in the region, stressing that there are no alternatives to a diplomatic settlement of the crisis in the region.
"The sides noted that there was no alternative to the settlement of the Nagorno-Karabakh crisis by political and diplomatic methods. In this context, specific parameters of further interaction were considered, primarily in the format of the OSCE Minsk Group", the Kremlin said.
Both leaders called on the parties to the conflict to "fully cease hostilities as soon as possible, de-escalate tensions, and exercise restraint".
The situation escalated on the contact line in Karabakh between Baku and Yerevan on Sunday, with both sides accusing each other of engaging in provocation on the line of contact.
Armenia and the authorities of the self-proclaimed republic, which has backed its independence aspirations since the early 1990s, have declared martial law and general mobilisation. Azerbaijan has declared partial martial law and partial mobilisation and shut down its airports to all international traffic except for Turkey, which has pledged support to Baku.
The escalation triggered a broad international backlash, prompting numerous countries and organisations to call on the warring parties to cease fire and return to OSCE-chaired negotiations.
