L. Paul Bremer, the U.S. civil administrator in Iraq, yesterday announced that the U.S.-led coalition regards the Kurdish Workers' Party, or PKK, as a terrorist organization. The PKK is accused of using northern Iraq as a base for staging attacks on neighboring Turkey, which has been engaged in a decades-long struggle with Kurdish rebels. Ankara welcomed Bremer's remarks, but some observers say the move may anger those Iraqi Kurds who do not consider the PKK a terrorist threat.
