埃及安全部队打死两名墨西哥游客

Egyptian security forces have killed 12 people, including Mexican tourists, after mistakenly opening fire on the visitors while the forces were pursuing terrorists in Egypt's western desert.

The Mexican Foreign Ministry said at least two of the dead were Mexican nationals.

Egypt said in a statement the dead were Mexican and Egyptian, but did not break down the death toll by nationalities.

The statement also said the area the tourists were in was "off limits to foreign tourists."

Rasha Azazi, a spokesperson for the Egyptian Ministry of Tourism, said the involved tour company did not have the proper permits and did not inform authorities that the tourists would be in the Farafra area. Azazi told the Associated Press that all trips to Farafra have to be cleared by authorities.

Mexican President Enrique Pena Nieto has demanded an investigation into the deadly incident.
