Dissident republican party Saoradh has been slammed for planning a Christmas Eve commemoration for two IRA bombers who blew themselves up and killed a teenager in Newry.
Aubrey Harshaw (18) died in 1973 along with two IRA members in the premature explosion, which killed all three men outside a bar on Monaghan Street.
Mr Harshaw was delivering a message to the bar when the bomb, carried by Edward Grant and Brendan Quinn, detonated, killing him instantly.
Saoradh have been linked to the New IRA.
The annual memorial service at Derrybeg Martyrs Monument draws condemnation every year.
Newry and Armagh DUP MLA William Irwin said he cannot overstate his objection to the event, especially as it eulogises two IRA terrorists who were planning on killing innocent people on Christmas Eve.
