Moscow has offered to help mediate demarcation negotiations after Armenia accused Azerbaijan of a border incursion, Russian Foreign Minister Sergey Lavrov has said.
Armenia accused Azerbaijan of sending troops across the border last week, highlighting the fragility of a Russian-brokered ceasefire that halted six weeks of fighting between ethnic Armenian and Azeri forces last year.
Azerbaijan has denied crossing the frontier and said its forces only defended their side.
But Armenia said on Friday that Azerbaijan had failed to fulfil a promise to withdraw troops that had crossed the border.
“Russia has offered first of all to provide assistance with the delimitation and demarcation of the border,” Lavrov told reporters during a visit to Dushanbe, capital of Tajikistan, on Wednesday.
