Leaders of Muslim states urged the immediate and unconditional withdrawal of ethnic Armenian forces from Nagorno-Karabakh in a declaration signed in Baku on Wednesday.
In a document called the Baku Declaration, the 57 member states of the Organisation of the Islamic Conference (OIC) said they "strongly condemn the aggression" of Armenia against Azerbaijan and "urge the immediate, complete and unconditional withdrawal of Armenian occupying forces."
The Armenian-majority enclave of Karabakh seceded from Azerbaijan in the late 1980s, sparking a six-year conflict between Armenia and Azerbaijan that claimed 25,000 lives and displaced hundreds of thousands of people. Despite a 1994 ceasefire, tensions remain high in the mountainous region -- one of the world's most militarized zones.
The OIC declaration called on member states to "support Azerbaijan on the issue of full restoration of its territorial integrity."
