Turkey's state-run news agency says Kurdish rebels have attacked police and judicial officials' lodgings with rockets in a further escalation of violence between the government and the insurgents.

Turkey's parliament is set on Wednesday to hold an extraordinary session — possibly behind closed doors — to discuss the attacks by rebels and the Islamic State group, and Turkey's response.

The Anadolu Agency says militants of the Kurdistan Workers Party, or PKK, fired at buildings in Hakkari province, near Turkey's border with Iraq, late on Tuesday. No one was hurt.

Turkish jets have been pounding rebel positions in northern Iraq and in southeast Turkey after the rebels claimed responsibility of killing two policemen last week. Turkish jets have also attacked Islamic State group extremists in Syria.
