At least 18 people were killed and 33 injured when a tourist bus overturned on a highway in Mexico’s western state of Nayarit, local authorities said on Sunday. The vehicle fell into a 15-meter-deep canyon Saturday night, killing 11 women and 7 men onboard, while the injured were taken to three hospitals in the state, the Nayarit State Attorney General’s Office said in a statement.

Enrique Alfaro, governor of the state of Jalisco, confirmed that the tourist bus left Tlajomulco in central Jalisco, heading for Guayabitos, a beach destination in Nayarit, where the passengers would be vacationing.
