Turkey's military says its warplanes have bombed 12 Kurdish rebel targets in northern Iraq. The military says in a statement posted on its Web site Sunday that the planes attacked rebel targets on Mount Qandil, on the Iraqi-Iranian border, where the rebel leadership is believed to be based. All planes returned to their bases safely, according to the statement. There has been no immediate comment from the rebel group. Turkey has conducted frequent air raids on suspected positions of the Kurdistan Workers' Party in northern Iraq. Earlier this year, it launched a weeklong ground offensive. The rebels have been fighting for self-rule in southeast Turkey since 1984. The violence has killed tens of thousands of people since then.
