Two people were killed and 32 injured when a Polish bus crashed Tuesday morning on a A36 motorway in north-eastern France, Poland’s Foreign Ministry said.

Several people were reported to be in serious condition.

The coach had been carrying 68 passengers who were mostly tourists from Slubice, a city on the German-Polish border. There were also Ukrainian nationals onboard.

It was not clear what caused the bus to veer off the road near the city of Mulhouse, close to the German border. One passenger said the driver of the bus suddenly swerved while emerging from the exit lane.
No other vehicle was involved in the crash.

More than 100 firefighters and 60 police officers were working on the wreckage of the bus, which was lying on its side, while emergency rescue service helicopters and about 150 rescuers were sent to the scene.
