The United States, Russia and France called for an immediate cease-fire as the ongoing conflict between Azerbaijan and Armenia over the mainly Armenian enclave of Nagorno-Karabakh entered its fifth day. The statement, signed by President Donald Trump, Russian President Vladimir Putin and French President Emmanuel Macron, called on the warring parties to resume negotiations for a peaceful resolution of the 32-year-old dispute over the mountainous area that Azerbaijan and Armenia both claim.

The three countries calling for a cease-fire are permanent members of the Minsk group established after the war first erupted between the former Soviet states in 1988, leaving Armenia in control of Nagorno-Karabakh and large swathes of Azerbaijani territory around it. Turkey backed Azerbaijan, while Iran helped Armenia. Russia played on both pitches, as it typically does in its former Soviet dominions to render itself indispensable.

Both Azerbaijan and Turkey have rebuffed the Minsk group’s calls for a cease-fire and vowed to fight on. Turkish President Recep Tayyip Erdogan apparently agrees that the war must go on. He said the Minsk group’s calls for a cease-fire were “unacceptable,” and if they were really seeking a solution, then Armenia had to withdraw from all the territories it had occupied and allow hundreds of thousands of Azerbaijanis displaced by the war to return.

Armenian Prime Minister Nikol Pashinian has ruled out any withdrawal, saying Nagorno-Karabakh is an existential matter for his nation of 3 million.
