Orthodox Christians across Alaska are taking part in three days of prayer for peace, ahead of a summit between U.S. President Donald Trump and Russian President Vladimir Putin.

The talks on Friday in Alaska pull the Russian leader out of diplomatic isolation from the West, and Ukrainian and European leaders fear it gives him an opening to sway the American president.

Donald Trump will host Vladimir Putin in Alaska - their first meeting in six years -as he tries to secure a Ukraine war ceasefire.
