A bus and a passenger train collided at a railroad crossing in this Pacific Coast port, killing 33 people and injuring 13, officials said Saturday.
Sinaloa state attorney Luis Zuniga Vizcarra, who is investigating the crash, said it occurred around 10 p.m. Friday. He said all the victims were Mexicans.
The train was bound for Nogales, on the Arizona border, when it crashed into the bus at the crossing.
The government news agency Notimex quoted unidentified investigators as saying preliminary findings showed the bus driver was listening to a loud radio and did not hear the train approaching.
