Armenia and Azerbaijan will not deploy third-country forces along their border after the two sides sign a peace agreement, Armenian Prime Minister Nikol Pashinyan said on Thursday.

But hurdles remain. Azerbaijan also said Armenia’s constitution must “eliminate the claims against the sovereignty and territorial integrity of Azerbaijan,” as a prerequisite to allow for the signing of the peace treaty.

Azerbaijan and Armenia said Thursday that they had wrapped up talks aimed at resolving the Caucasus neighbours' decades-long conflict, with both sides agreeing on the text of a possible treaty.
