The Taoiseach Bertie Ahern has offered his condolences to people caught up in this morning's explosions in London.
British police are investigating at least six blasts.
They have refused to speculate on the cause, but the explosions bore all the hallmarks of a co-ordinated attack by Islamic militants.
Speaking this morning in Rome, where he is due to meet Pope Benedict XVI, the Taoiseach said his thoughts and prayers were with all those affected by the blasts.
