“Indeed, the penalty for those who wage war against Allah and His Messenger and strive upon earth corruption is none but that they be killed or crucified or that their hands and feet be cut off from opposite sides or that they be exiled from the land. That is for them a disgrace in this world; and for them in the Hereafter is a great punishment.” (Qur’an 5:33)
“Egypt: ISIS beheads Egyptian in western desert,” ANSAmed, September 14, 2015 (thanks to Insubria):
(ANSAmed) – CAIRO, SEPTEMBER 14 – Eight jihadists with ISIS have beheaded an Egyptian in the Egyptian western desert and crucified him to a tree after accusing him of cooperating with police. According to local sources, the beheading yesterday occurred in the same area where tourists were killed in an anti-terror raid by Egyptian police.
Witnesses added that local residents asked for the police to intervene to find the killers who fled aboard a jeep, a similar model to the one used by tourists killed in the same area.
Meanwhile local sources said that the Egyptian army killed seven jihadists from ISIS also in the same area of el Wahat, in the western desert. Libyan sources stated that the jihadists had fled from Derna after being chased away by the Libyan army.

Terrorists posing as tourists?

Still showing their stupidity in everything they do.
Baucent says
ISIS in Egypt is showing the classic insurgent methodology; Terrorize a local community you are trying to infiltrate. Those associated with the local authorities killed as an example. Force the local population to support and feed you.
The Mexican tourist killed this week by an Egyptian attack helicopter were probably mistaken for these very same Jihadists who killed the Copt. Tragic mistake but only a fool would be touring in that desert.
