WATCH: Video footage from the crash site (Reuters)
Officials and news reports say a bus carrying Russian tourists has skidded off a highway in southern Turkey and fell off a bridge, killing 16 passengers and injuring 25.
NTV television footage showed the bus had flipped over and had fallen about six meters onto a river bed.
Deputy Governor Mehmet Seyman of the Mediterranean province of Antalya said rescue workers struggled to pull the bodies and injured from the wreckage.
The bus was traveling from the resort of Alanya to the Pamukkale waterfall near the central city of Denizli. NTV television, citing local authorities, said the driver fell asleep at the wheel.
Each year, thousands of people are killed in traffic accidents on Turkey's roads because of careless driving or poor road conditions. About 3 million Russian tourists visit Turkey annually.
