Russia offers to help demarcate Armenia-Azerbaijan border

Move by Moscow comes after Armenia accused Azerbaijan of sending troops across the border last week.

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.
