A bus bound for Mayan ruins in eastern Mexico has crashed, killing at least 12 tourists.
Carrying passengers from cruise ships out of Miami and Fort Lauderdale, the bus apparently flipped on a two-lane highway, Associated Press reported.
According to AP, Quintana Roo state Civil Defense spokesman Vicente Martin said authorities were yet to determine the nationalities of the dead, but Americans and Europeans were among the injured.
He added that investigators were working on the cause of the crash, which happened en route to the Chacchoben ruins 175 kms south of Tulum.
Passengers from two Royal Caribbean vessels, the Celebrity Equinox and Serenade of the Seas, were involved in the accident, said a statement from RCL, which is assisting with medical care and transportation.
Chris Bawley, a passenger on Serenade of Seas, arrived on the scene just minutes after the incident at 9am.
On a bus headed to the same site, he said the weather was clear, the road was dry, and there didn’t appear to be any other vehicle involved in the crash.
"… the bus clearly lost control somehow as there were swerve marks all over the road surface," he said.
