At least 14 people died after a bus travelling between the Spanish cities of Valencia and Barcelona crashed early on Sunday (March 20), a local government official said, adding it had been carrying a group of university students, many of them foreign.
The bus was carrying 56 passengers, according to officials in the northeastern region of Catalonia.
Many of the students onboard were participating in an exchange program between European universities known as Erasmus.
The bus crashed and overturned at around 0600 local time (0500 GMT) on a highway than runs along Spain's eastern coast.
The bus had been travelling from Valencia, on the last weekend of a major festival known as the Fallas which is known for its exuberant firework displays and attracts many tourists.
The nationalities of the deceased were not confirmed. The driver survived the collision and had been taken to a local police station, officials said.
A heavily damaged car could be seen near the overturned bus at the crash scene, although the cause of the accident was not immediately clear. Most of the remaining passengers had not sustained life-threatening injuries, officials said.
