ANCHORAGE (AP) — Orthodox Christians across Alaska have been taking part in three days of prayer for peace ahead of Friday’s summit there between U.S. President Donald Trump and Russian President Vladimir Putin, which will focus on the war in Ukraine.

“The symbolism of Alaska would be a reminder of how it was possible for the United States and Russia for most of the 19th century to transcend their ideological and political differences and their expansionisms, to have warm, friendly cooperative relations,” says David S. Foglesong, a history professor at Rutgers University - New Brunswick.

President Donald Trump and Russian President Vladimir Putin head to Alaska on Friday for a high-stakes summit as the U.S. seeks a ceasefire in the Russia-Ukraine war.
