IRISH REACTION: Minister for Foreign Affairs Dermot Ahern strongly condemned "the attempt to strike fear and terror into the community" in London.
"I strongly condemn these actions. Coming so soon after the appalling terrorist attacks of July 7th, they are utterly callous and unjustified," Mr Ahern said.
"I want to offer my wholehearted support to the people of London in resisting this further attack and to express my appreciation to the security and emergency services there who are, once again, called on to protect the community.
"I have no doubt that the British government will actively pursue those who carried out these attacks and bring them to justice.
"Those responsible should know that they will not deter the international community from combating terrorism vigorously and uncompromisingly wherever it occurs.
"I have instructed our embassy in London to monitor the situation closely.
"For the time being, I would urge all Irish citizens in London to contact their families to assure them that they are safe and to follow the advice of the security authorities."
