Turkey and the US are locked in a heated dispute about US plans to liberate Raqqa, with Turkey suggesting its own military and allied forces in Syria should mount the fight.
Yildirim says Turkey wouldn't be part of any operation including the Syrian Kurdish force.
He tells The Associated Press on the sidelines of a meeting with visiting foreign journalists that "if the U.S. were to prefer terrorist organizations over Turkey in the fight against IS, that would be their own decision." But he says Turkey wouldn't consent.
