The long-awaited release of Nazanin Zaghari-Ratcliffe after six years in detention in Iran leads many of today’s papers. The Guardian’s front page shows a smiling Ms Zaghari-Ratcliffe on a plane after taking off from Oman as part of her return to the UK. The paper also reports on an alleged Russian airstrike on a theatre in the besieged Ukrainian city of Mariupol in which hundreds of people are thought to have been sheltering.
