A passenger bus traveling on a highway in Hungary early Sunday went off the road and into a ditch where it overturned, killing 12 people and injuring at least 10 others, police said.

The bus, which was carrying a group of Polish tourists, was traveling on eastbound lanes near the town of Mezokeresztes when it overturned on the M3 motorway around 140 kilometers east of Hungary’s capital, Budapest, at around 1 a.m. on Sunday.

According to police, it is likely that the driver fell asleep, causing the accident, and the driver had been taken into custody.

Hungary’s National Directorate for Disaster Management reported that 57 passengers and two drivers were on the bus at the time of the accident, with several passengers trapped under the vehicle when it overturned.

The bus was carrying people from Poland’s southeastern Podkarpackie region who were returning from a pilgrimage in Bosnia-Herzegovina.

Hungarian Prime Minister Péter Magyar and Polish President Karol Nawrocki expressed their condolences to the families of the victims.
