A long-serving prison officer has been murdered in a motorway ambush by dissident republicans in Northern Ireland.
David Black, from Cookstown, Co Tyrone, had more than 30 years' service in the Prison Service and was approaching retirement.
He was ambushed by a gunman on Northern Ireland's M1 motorway early on Thursday morning as he drove to begin duty at the top security Maghaberry jail near Lisburn, Co Antrim.
Politicians on all sides condemned the murder and, even though no organisation has admitted responsibility, security chiefs believe republicans opposed to the peace process were involved.
The extremists have been involved in long-running protests against jail conditions inside Maghaberry.
