Azerbaijan’s President Ilham Aliyev and Armenian Prime Minister Nikol Pashinyan signed an agreement brokered by U.S. President Donald Trump to end a decades-long conflict over the Nagorno-Karabakh region.

“Congratulations to President Trump! Your bold leadership and global vision have made another peace agreement possible,” Prime Minister Benjamin Netanyahu tweeted. “I also congratulate President Aliyev, Prime Minister Pashinyan, and the peoples of Azerbaijan and Armenia on signing this historic agreement.”
