A bus carrying tourists from a cruise ship has overturned in south-eastern Mexico, killing 11 people, officials say.
Another 18 people were injured in the crash on a road between Mahahual and Cafetal in Quintana Roo state.
The bus was taking 31 people, who were on a Royal Caribbean cruise, to the ancient Mayan ruin at Chaccobén.
Those on board were nationals of the US, Italy, Sweden and Brazil, a bus company statement said.
A local driver and tour guides were also said to be on the trip.
The injured were taken to four local hospitals and five people were discharged, the Costa Maya company said.
Bus crashes are common in Mexico where people often travel along dangerous routes at night – but an accident involving the deaths of so many tourists in broad daylight is rare, the BBC Mexico correspondent Will Grant says.
It is not known what caused the crash. Photographs have now emerged showing the vehicle on its side with dazed survivors sitting nearby.
Emergency services are at the scene helping the injured.
