Eight people were killed and some 35 were injured, with four in critical condition, after an intercity bus toppled off a highway in Turkey's western Afyonkarahisar district, Governor Kubra Guran Yigitbasi told state media.
The passenger bus was on a cross-country route from Diyarbakir in the east to the western resort city of Bodrum.
The driver lost control of the steering wheel in the high-altitude region, Yigitbasi was cited as saying by broadcaster TRT. She gave no further details.
