There have been renewed calls for an independent investigation into the death of a journalist in Northern Ireland 18 years ago.
Martin O’Hagan, from Lurgan in Co Armagh, was murdered by the Loyalist Volunteer Force (LVF) on September 28, 2001.
The 51-year-old had been returning home with his wife Marie when he was shot.
The National Union of Journalists (NUJ) in Ireland and the UK made a joint statement ahead of the anniversary of his death.
The Sunday World investigative journalist had been an active member of the union.
Michelle Stanistreet, NUJ general secretary and Séamus Dooley, NUJ assistant general secretary, today called for an external investigator to be appointed to carry out an independent inquiry into Mr O'Hagan's murder.
In the statement, the NUJ said it was "gravely concerned" Mr O'Hagan's killers had not been brought to justice.
It said: "The cold blooded killing of a courageous investigative journalist should be investigated by an independent body.
"There are so many unanswered questions about the murder of Martin that the case should be urgently reviewed.
It said Mr O'Hagan's family, colleagues and friends "continue to mourn a journalist of integrity and bravery".

The union said the onus was on the UK government to show political leadership on the issue as part its commitment to press freedom.
It also called on the Irish government, as co-guarantors of the Good Friday Agreement, to support its request.
Earlier this month, the editor of the Sunday World also called for a fresh investigation to be launched.
Mr O'Hagan was is one of two journalists from Northern Ireland who have been murdered.
In April of this year, Lyra McKee was shot and killed during riots in the Creggan area of Derry.
