Mexico's FM heads to Cairo for answers on tourist killings

Mexico's foreign minister was headed to Cairo on Tuesday with relatives of tourists mistakenly killed by Egyptian security forces, after her government demanded an urgent investigation into the "unjustified attack".

Claudia Ruiz Massieu flew out of Mexico City late on Monday vowing to seek answers from Egyptian authorities on the attack that killed 12 people, including at least two Mexicans.

Egyptian authorities have said the tourists entered a restricted area in the country's vast Western Desert and were "mistakenly" killed while security forces chased jihadists who had abducted and beheaded an Egyptian they said worked for the army.
