The Taoiseach has described the bombings at the Boston Marathon as an act of insanity.
Enda Kenny has expressed his sympathy to the people of Boston in a city he described as being "so Irish".
And he expressed his hope that the people responsible for the explosions that killed three and injured around 140 people will be brought to justice as soon as possible.
Speaking on his way into Government Buildings this morning the Taoiseach said he met with the Governor of Massachusetts last year and will welcome him to Ireland on a trade mission next month.
"This is an act of insanity. When so many people enjoyed the preparation for that wonderful race and the occasion itself" he said.
"We sympathise with the people of Boston in a city that is so Irish - this is a tragedy".
"I do hope that the authorities - from Federal level down to local level - will get to the root of this, and bring those perpetrators of this particular crime to justice in the shortest possible time" he added.
