Armed Gardaí are to patrol Dublin Airport following the terror attacks on Brussels.
The heavily-armed, SWAT-style, police will be stationed there permanently, it has been widely reported in Irish news media, citing official security sources.
It follows the ISIS terror attacks in Belgium in which 31 people were killed in suicide gun bomb and gun attacks at the city’s Zaventem airport and its Maalbeek metro station.
The Gardaí will be part of a new Regional Support Unit guarding both terminals.
The unit was originally established earlier this year in response to a spate of gangland murders.
The RSU police will carry machine pistols and side arms.
Senior Gardai, who had been planning to implement the armed overt armed patrols for some time, made the decision on Wednesday.
No date has been given for the start of the patrols other than to say it will be in the coming months.
The 55-strong unit will also patrol areas of Dublin in high-powered 4x4s.
Meanwhile in the UK Heathrow, Gatwick and Manchester airports are among those where security was stepped up following explosions in the Belgian capital on Tuesday.
Eurostar passengers have been told to allow one hour due to “enhanced security checks”.
