Iraq's president, a Kurd, said Monday that Kurdish rebels will announce a cease-fire, his office confirmed, as tensions soared over a Turkish threat to stage a cross-border incursion against guerrilla bases in northern Iraq.

President Jalal Talabani said the Kurdistan Workers' Party, know by its Kurdish acronym PKK, would make the announcement later Monday.

Talabani's remarks were made to reporters at the airport in the Kurdish city of Sulaimaniyah before he flew to Baghdad and confirmed by his office. More details were not immediately available.
