Turkish officials say Kurdish rebels have attacked multiple police facilities in southeastern Turkey, killing at least three people.

Officials say gunmen opened fire on two police buildings late Sunday in the mainly Kurdish province of Hakkari, which lies along the Turkish-Iraqi border.

Turkish police say a firefight between the rebels and police ensued, leaving civilians in the crossfire.

Authorities say at least 10 people were wounded.

The outlawed Kurdistan Workers Party, or PKK, has escalated attacks in recent weeks, while Turkish forces increased their airstrikes against suspected rebel bases in northern Iraq.

The PKK is fighting a nearly 30-year-long guerrilla war for an independent Kurdistan and more civil and political rights for Kurds living in Turkey.

Turkey, the European Union and United States regard the PKK as a terrorist group.
