At least 10 people were killed and 16 others injured Wednesday when a minibus packed with children on a day trip slammed into a house in the southwestern state of Michoacan, Mexico, local police sources said in a statement.

The accident took place in the town of Uruapan, about 600 kilometers southwest of Mexico City, the national capital, around 11:30 a.m., local time, when the vehicle, which was rented to take a group of children to a local zoo, suddenly veered off the highway and crashed into the house.

The injured were all hospitalized. Among the critically injured were kindergarten and elementary school children, some of whom were airlifted to hospitals for emergency treatment.

It is not immediately known the exact number of people aboard the ill-fated bus. The house also sustained partial damage in the accident.

No other details, such as the cause of the accident, were available for the moment.
