U.S. Secretary of State Condoleezza Rice flew to Ankara on Friday for talks aimed at averting large-scale military action by Turkey against Kurdish rebels in northern Iraq. Rice called the outlawed Kurdistan Workers Party (PKK) a "common enemy," and vowed to redouble U.S. efforts to help Turkey tackle the problem. Washington is opposed to military action in an area that's so far been spared the worst of the violence in Iraq. Dozens of Turkish soldiers have been killed in recent weeks in clashes with PKK guerrillas and the Turkish government is under huge domestic pressure to wipe out Kurdish rebel bases in northern Iraq.
