Romania's foreign ministry said later on Friday that the bus was carrying 32 Romanians who were traveling to Italy. The statement said four people received medical care.

Photos from the scene showed the bus on its side in the grass beside the road. Marks can be seen where it apparently slid down a grassy slope after breaking through a barrier.
