Two Turkish soldiers were killed and four wounded in a car bomb attack on their convoy in the mainly Kurdish southeast of the country, the local governor's office said Sunday.

The car bomb went off as the soldiers were travelling on a road in the Lice district of the Diyarbakir province late Saturday, the statement said, after the Kurdistan Workers Party (PKK) rebel group threatened to no longer observe a truce following Turkish air strikes on its positions in northern Iraq.
