Secretary of State Condoleezza Rice says there is a common interest among the United States, Turkey and Iraq to stop Kurdish rebels in northern Iraq.
But Rice -- on an unannounced visit to Iraq -- is warning against taking any action that could destabilize the region.
Her comments come two days after Turkey conducted airstrikes in northern Iraq that involved as many as 50 jets. Iraqi officials say the planes attacked several villages, killing one woman.
Rice made it clear the United States supports efforts to quash any rebel movement, but she said it was a "Turkish decision" to act.
She also suggested that Iraqi, Turkish and U.S. authorities try to work together against the rebels.
