Mexico's foreign minister has arrived in Egypt after Egyptian security forces mistakenly killed at least eight Mexican tourists on a desert safari.

Secretary of Foreign Affairs Claudia Ruiz Massieu touched down in Cairo early Wednesday morning, accompanied by several family members of the victims, according to a statement from the Mexican Foreign Ministry.

Massieu will visit survivors of the incident and also meet with Egyptian officials, "to obtain first-hand information that would clarify the circumstances of this deplorable event," the statement said

Egyptian officials initially claimed the convoy of SUVs had wandered into an off-limits area of Egypt's western desert. But in an open letter to the Mexican people, Egyptian Foreign Minister Sameh Shoukry said the facts of the case remain "confusing" and promised a thorough and impartial investigation.
