Gardaí are questioning two men arrested after explosives were discovered in a car in Dublin last night.

The men in their early 30's and 40's were arrested on the Naas Road after the car they were driving was stopped by the Emergency Response Unit at about 7.30.

The bomb squad was called to the scene and the device has now been sent for forensic examination.

The men are being detained at Ballyfermot and Ronanstown stations.
