Eleven people, including nine high school students, have been killed after their vehicle struck a trailer on a Mexican highway.
The group were killed in the central Mexican state of San Luis Potosi after their vehicle collided with a freight truck's trailer.
The trailer broke off the back of the truck and hit the vehicle with the students near the town of Rayon in the northern part of the state, said the Ministry of Public Security.
Early reports suggest the students were returning from taking a university entrance exam.
Two adults were also killed.
The truck driver was not hurt and has been detained while the accident, which happened on Tuesday, is investigated.
