The IRA has said a demand for its "humiliation" prevented agreement on a comprehensive peace deal prior to Christmas.

In its New Year statement, published by An Phoblacht on Thursday, the terrorist organisation said it remained committed to the peace process.

"Time and again over the past 10 years the IRA has demonstrated its commitment to the peace process," it said.

"On occasion, our initiatives have stretched the discipline and patience of our volunteers and the wider republican base. To their credit, they have remained steadfast."

The last attempts to reach a deal foundered on demands by the Democratic Unionist Party for photographic evidence of the IRA's decommissioning.

DUP leader Rev Ian Paisley's provocative statements concerning the treatment of the paramilitary organisation prompted anger from republicans.

The IRA said it was "prepared to make to a comprehensive agreement to resolve all outstanding issues".

"This included moving into a new mode which reflects our determination to see the transition to a totally peaceful society and also concluding the process to completely and verifiably put all our arms beyond use," said the statement.

"All of this is being prevented by an unachievable demand for humiliation.

"The rejection of our substantial contributions has created a deep anger within the republican and nationalist communities and indeed it has generated significant frustration."

The statement said that a "just and lasting peace is only possible on the basis of equality".

"The days of inequality and of discrimination are over. There must be an end to bigotry, sectarianism and racism."

It also warned the British and Irish governments against "pandering" to unionist demands.

The IRA repeated its call for "the unity and independence of Ireland".

"While a peace process can produce an accommodation, and the IRA is prepared to assist this process, Irish unity and independence provides the best context for the people of this island to live together in harmony and prosperity," it said.

"We remain committed to our republican objectives."
