A Garda terrorist training exercise took place in the Docklands earlier today.
The exercise was to test how various Garda units would respond to a coordinated terrorist attack.
The Docklands railway station was closed while it took place.
The simulated operation involved a fake stabbing and hostage situation.
Superintendent Sean Ward says it’s been a long time in the planning, and noted "there'll be further exercises later on in the year".
