The leaders of Armenia and Azerbaijan shook hands as they joined President Donald Trump at the White House on Friday for a peace summit where they signed an agreement aimed at ending decades of conflict.

President Donald Trump was in the middle as Azerbaijani President Ilham Aliyev and Armenian Prime Minister Nikol Pashinyan flanked him on either side. As the two extended their arms in front of Trump to shake hands, the U.S. leader reached up and clasped his hands around theirs.

Armenia and Azerbaijan published the text of a U.S.-brokered peace agreement on Monday, pledging to respect each other's territorial integrity and formally put an end to nearly four decades of conflict.
