Egyptian security forces have killed 12 tourists and guides in the country’s Western Desert, after mistaking a tourist convoy for a convoy of terrorists.

Mexico’s foreign ministry has said at least two Mexicans were killed in the attack.

The attackers were a joint force of Egyptian police and military.

The tourist convoy was made up of four wheel-drive vehicles.

In a statement issued through Twitter, Mexico’s President Enrique Pena Nieto called for an investigation into the incident.

“Mexico condemns these deeds against our citizens and has demanded an exhaustive investigation of what has occurred,” he said.

The convoy was in an off-limits area and was using unlicensed cars, according to comments made to Egypt’s state news agency by a tourism ministry spokesman.
