Four-minute response time to terror attack training exercise

A counter-terrorist attack training exercise, with mass casualties, has been carried out by An Garda Síochána.

It took four minutes for a patrol vehicle to arrive at the scene and then it was another four minutes until the Armed Support Unit was on site.

The exercise took place at a train station in Dublin city centre yesterday morning in real time, with responding gardaí unaware of the location or details of the attack.
