A new republican paramilitary group calling itself the IRA is claiming responsibility for the murder of prison officer David Black earlier this month.
In a statement released to the Irish News in Belfast - the group say the killing was in direct response to the conditions in Magaberry Prison, where Tyrone born Mr. Black worked.
52-year-old father of two David Black was shot dead on the M1 in Co Armagh on the First of November as he drove to work.
Today a newly formed republican paramilitary group calling itself the IRA has claimed responsibility for the killing.
In a statement to the Irish News newspaper group in Belfast the group said it is a successor to the provisional IRA which disbanded after the Belfast agreement in 1998.
The new organisation is a coalition of dissident groups formed earlier this year.
It said the killing was a direct response to what it said was the degradation of Republican Prisoners at Magaberry jail where nationalists have been protesting against strip searches.
