GARDAÍ AND EMERGENCY services are at the scene of a five-car pile up on the M7 Limerick/Dublin road northbound, just before junction 10 Naas South.
The crash has been moved to the hard shoulder. However, the AA are reporting long delays on approach from Junction 11 M9 and onlookers are also causing a slow down southbound.
Care is required in the area as conditions are very foggy.
Gardaí are unsure at the moment if anyone has been hurt in the incident.
