The Northern Ireland Secretary has said the DUP blocked a deal that could have restored powersharing at Stormont.
The DUP said there is still a significant amount of work to be done to achieve a "fair and balanced" agreement.
Julian Smith said that he was "deeply disappointed" and has asked the party to reflect on its decision.
He was meeting the five main political parties in Northern Ireland and Tánaiste Simon Coveney today in an attempt to restore the devolved institutions.
He had also convened a "health summit" to discuss the health service crisis in the North.
Speaking this evening, Mr Smith expressed his disappointment that the parties could not reach an agreement before Christmas.
He said the DUP was "a crucial part" of the new Stormont and urged the party to "move forward" to get powersharing restored.
Sinn Féin's chief negotiator Conor Murphy also said that the party "is deeply disappointed that the DUP are telling the media and the public the talks have to be closed down for Christmas".
He said: "Sinn Féin has been committed to doing a deal, and that deal can be done in the coming days.
“There is an onus on us all to reach an agreement, to give the people hope, to address the outstanding issues and get back into institutions, which work for all.
"The onus is now on the DUP, once again, to tell the public why they are now holding up the restoration of the Assembly.”
