Wilayat Sinai terrorist group killed two civilians in North Sinai's Arish city, Al-Bawaba News reported Sunday. Security services investigations revealed that Wilayat Sinai militants killed the two over claims that they were cooperating with the Egyptian army. During the last 72 hours, Wilayat Sinai killed 11 people in North Sinai's Arish and Rafah city for cooperating with the army and police. Since September 2013, the Egyptian army has been carrying out an ongoing military campaign against Wilayat Sinai, formerly known as Ansar Bayt Al-Maqdis, after it had claimed responsibility for several attacks targeting Egyptian military and police personnel.
