Kurdish rebels are threatening to extend their uprising in southeastern Turkey to other areas of the country, if the military continues its ongoing offensive against rebels in the region.

In a published statement Tuesday in the pro-Kurdish newspaper Ozgur Politika, rebel commander Yusef Turhalli said his forces will begin targeting Turkey's larger cities if the offensive continues.

Meanwhile, Turkey said four soldiers were killed today, when a rebel-planted bomb destroyed their vehicle near the Iraqi border.

Hours earlier, police said two Kurdish suicide bombers linked to the outlawed Kurdistan Workers Party (the PKK) were killed in a failed attack on the local governor's residence.

Fighting subsided in 1999 after the PKK declared a cease-fire with Ankara in its 15-year battle for Kurdish autonomy in the region. But rebels called off the truce last June, saying they were not satisfied with the pace of promised Turkish reforms.
