A Czech bus carrying about 50 passengers crashed near a tunnel in Croatia early Saturday, killing seven people and injuring at least 44, the national rescue services said.
"A bus with Czech licence plates drove through a safety barrier and turned over" near a tunnel in Sveti Rok, some 230 kilometres (138 miles) south of Zagreb, the National Protection and Rescue Directorate said.
The accident occurred around 4:00 am (0200 GMT) on the road to the Adriatic city of Split, a popular tourist destination.
The injured were taken to a hospital in nearby Gospic, while victims with serious injuries were being transferred by a military helicopter to the capital Zagreb, the rescuers said.
Local media said the bus hit the barrier, turned over and smashed into a concrete fence opposite. There were 50 passengers, police spokeswoman Kristina Maodus told Nova TV.
All of them were Czech nationals, the channel said, quoting unconfirmed reports.
