The Russian Consulate in the Greek city of Thessaloniki has confirmed that four Russian tourists were killed and 30 injured when a bus that was taking them to the airport crashed in the predawn hours.
The Greek driver of the bus was also injured.
There were reportedly 50 Russians on the bus -- 49 tourists and a guide -- and they were scheduled to depart on a flight to St. Petersburg on September 14.
The bus apparently skidded off the road in a light rain and overturned.
