A 'Real IRA' bomb warning has led to the closure of the rail line between Newry and Dundalk.
The line has been shut since yesterday and Iarnród Éireann says it expects the line to remain closed until tomorrow.
The 'Real IRA' claimed it had placed devices beside the track at the same time as it placed incendiary devices in a number of shops in Newry earlier this week. These detonated starting fires which led to extensive damage, but no injuries.
While the railway is out of service passengers are being transferred by bus.
