Northern Ireland Secretary Theresa Villiers has condemned an attempted letter bomb attack after a viable device was found at a postal sorting office in Londonderry.
Ms Villiers said, "Once again these individuals have demonstrated a completed disregard for our postal workers and the local community. Anyone with any information should pass it to PSNI [Police Service Northern Ireland]."
Stormont's Deputy First Minister will hold talks with the Northern Ireland Secretary as a political crisis triggered by the collapse of the Hyde Park bombing case continues to threaten the future of the devolved administration in Belfast.
Sinn Fein's Martin McGuinness and Theresa Villiers are set to meet at Stormont Castle to discuss the controversy that prompted First Minister Peter Robinson to threaten to resign.
The Democratic Unionist leader has effectively given the UK Government 24 hours to respond to his demand for a public inquiry into secret letters sent to IRA suspects that assured them they would not be prosecuted.
Northern Ireland Secretary Theresa Villiers said the information contained in the de Silva report made "exceptionally difficult" reading for the Government. She said the report uncovered new, shocking information:
"I think this is genuinely an exceptionally difficult day for the British Government, because we are presented with the facts of state involvement, the involvement of paid state agents in a killing, which is utterly unacceptable, utterly devastating"
Northern Ireland Secretary Theresa Villiers told the House of Commons there was nothing British about the 'thuggish, lawless and despicable" behaviour of loyalist protesters. She said:
"There is nothing remotely British about what they are doing; they are dishonouring and shaming the flag of our country with their lawless and violent activities.They discredit the cause they claim to support."
Her comments came as the First Minister of Northern Ireland Peter Robinson said two senior members of his party were issued with death threats. Marc Mallet reports from Belfast.
