The President, Mrs McAleese, has sent a message of sympathy to Queen Elizabeth on behalf of the people of Ireland following the terrorist attacks in London this morning.
In her message, Mrs McMAleese expressed her shock and horror at the scale of the attacks and said they serve no cause except the cause of evil.
"Today, which should have been a day of righteous celebration for Londoners, having successfully won the bid for the 2012 Olympics, has been turned into a day of cruel and vicious waste of innocent human life," she said.
"In our world, the espousing of hatred will not resolve our problems but will exacerbate them. I offer my deepest sympathy and solidarity to the families of the bereaved and to all the injured," she concluded.
The President has also telephoned the British abassador to convey her outrage and her sympathy.
