The shooting of Detective Chief Inspector John Caldwell in Omagh stirred painful memories - not just of The Troubles but more recent violence. The young journalist Lyra McKee was fatally shot while covering rioting in Londonderry in 2019. Police have investigated links with dissident Republicans with both the attacks.

Father Martin Magill, a Catholic priest from the Falls Road in Belfast, gave a powerful speech at Lyra McKee's funeral. He spoke to Today's Martha Kearney about this latest violence.
