The world’s media watches as the presidents of Russia and the USA meet in Alaska. Russian officials say they want to discuss broad US-Russian relations, but on Air Force One President Trump said he wanted to focus on Ukraine.

Also on the programme: we hear from an Indian soldier who saw the aftermath of the atomic bombing of Hiroshima and Nagasaki; and the people trying to crack an unsolved code sitting right outside the CIA’s headquarters.
