A Catalan regional government official says the 13 female students killed in a bus crash in northeastern Spain this weekend were all from other countries, including seven from Italy.

Interior department director Jordi Jane said Monday the other six included two Germans, an Austrian, a French woman, a Romanian and an Uzbekistani.

Jane told reporters the victims were aged between 19 and 25 years.

The bus carrying 57 university students crashed Sunday near Freginals, halfway between the eastern coastal cities of Barcelona and Valencia. They were returning from a firework festival in Valencia.

The students were studying in Barcelona as part of the Erasmus exchange program.
