Egyptian security forces killed 22 suspected militants who were planning to target security forces in the restive North Sinai province on Monday, security sources said. Egypt is facing a Sinai-based insurgency that has killed hundreds of policemen and soldiers since the army toppled Islamist President Mohamed Mursi after mass protests against his rule in 2013. The sources said security forces struck a group of people meeting outside a mosque south of the Sheikh Zuwayed town who were planning an attack on security points. They also targeted a vehicle with four militants and two more riding a motorcycle. Earlier on Monday at least eight policemen and civilians were wounded when explosions hit two houses in El-Arish, the provincial capital of North Sinai, security and medical sources said.
