ANKARA, Turkey — Turkish warplanes struck Kurdish rebel positions overnight in southeast Turkey, the military said Tuesday, a day after heavy violence in the country left at least nine dead.

In a statement, the Turkish military said jets hit 17 targets of the Kurdistan Workers’ Party, or PKK, around the Buzul mountain and the Ikiyaka region in Hakkari province, which borders Iran and Iraq.

In further violence Tuesday, Kurdish rebels attacked an infantry brigade command post in nearby Sirnak province, seriously wounding a soldier who later died in a hospital.

On Monday, nine people, including five police officers, were killed in separate attacks in Istanbul and in the southeastern Sirnak province. The attacks were blamed on the PKK.
