French President Emmanuel Macron said on Thursday that the agreement of peace treaty terms between Armenia and Azerbaijan should open the way for a lasting peace deal in the region.

Armenia and Azerbaijan have fought a series of wars since the late 1980s, when Nagorno-Karabakh, a region in Azerbaijan that had a mostly Armenian population at the time, broke away from Baku with Yerevan's support.

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.
