ANKARA, Turkey, Jan. 23 (UPI) -- A bus overturned Thursday in the central Turkish province of Kayseri, killing at least 21 people and injuring 29 others, police said.
The driver of the bus, Ertugrul Karasu, lost control around 2:30 a.m., local time, near the Olukkaya neighborhood in the Pinarbasi district, Cihan news agency reported.
The bus veered off the snow-covered highway and tipped onto its side after striking the road barrier. The bus tumbled several times before sliding into a ditch, the Hurriyet Daily News reported.
Police said fog and icy road conditions may have triggered the crash but are also investigating whether the driver fell asleep at the wheel.
