Overnight talks in Belfast have failed to resolve deep-seated divisions over parades and flags that have triggered widespread rioting in Northern Ireland.
Richard Haass, director of the New York-based Council on Foreign Relations, led the multiparty talks.
The hope was that he could forge a compromise plan by the end of the year on areas of bitter dispute: parades, British and Irish flags and emblems, and remembering the dead from Northern Ireland's four-decade conflict.
Talks ended around 4am on Tuesday without agreement.
Haass insisted the process was "still alive" and said he might return to Belfast before the end of the year.
