The gardaí say any threat of terrorism in Ireland is unlikely, despite plans for up to one million people to attend events this weekend to commemorate the 1916 Rising.
It comes after 34 people died in attacks at the airport and a metro station in central Brussels yesterday.
The centenary events this weekend will be the largest in the history of the State.

They will include an Easter Sunday Parade, involving 3,700 members of the Defence Forces.
Up to 500,000 people are expected to line the streets of Dublin to watch the parade.
Assistant Garda Commissioner for Dublin is Jack Nolan.
He says although the terrorism threat in Ireland is considered low, we are not immune.
