Egyptian forces inadvertently kill tourists during hot pursuit of terrorists

An Egyptian military operation against terrorist elements went badly awry on Sunday when security forces opened fire on a convoy of Mexican tourists and their local guides in a desert area, killing at least 12 people and injuring 10 others.      .  
The attack took place in the Wahat area of Egypt’s Western Desert, a region where there have been sporadic attacks by Islamic militant groups.
According to a statement by the Egyptian Interior Ministry, the security forces were in pursuit of Islamic militants when they targeted the four vehicles, which were away from the main road, with an Apache helicopter.
At least two of those killed were Mexican citizens. In a Twitter post, Mexico's President Enrique Pena Nieto condemned the attack and said he had "demanded an exhaustive investigation by the Egyptian government."
