Dissident republicans are being blamed for a bomb which exploded near the border of Northern Ireland today.
No-one was injured in the blast but a second device was discovered during the security alert outside Newry, Co Down.
Army technical experts carried out a controlled explosion on that device.
The main Belfast to Dublin railway line was closed for a time and the traffic on the arterial road South was also delayed.
Police said the second device was capable of causing death or serious injury and caused major disruption in the community.
