Police ordered the emergency evacuation of Dublin International Airport on Tuesday after a man claiming to have a bomb in a suitcase was arrested in the airport's arrivals hall.
Ireland's national police force, the Garda Siochana, said several of its units and the Irish army bomb squad were being dispatched to the airport, which is about 15 kms north of central Dublin, but no explosive device was immediately found.
Siobhan Moore, spokeswoman for the Dublin Airport Authority, said all travellers and staff had been evacuated from the airport terminal to nearby car-parking spaces or to the sidewalks outside, while all flights out of the airport would be grounded until the bomb threat was resolved.
She said incoming flights were being told to maintain a holding pattern for now. She said the evacuation and runway shutdown had delayed about 20 flights so far.
Moore said police had no choice but to presume the man had a bomb. "If somebody walks into the terminal building and makes a declaration like that, we have to take it seriously," she said.
But police advised would-be travelers to keep coming to the airport, because their flights were likely to take off later Tuesday subject to lengthy delays.
