Egyptian police forces have killed 11 militants in the northern Sinai Peninsula, after several attacks in the last two days have left eight policemen and three civilians dead in the restive area. An Interior Ministry statement Thursday said security forces exchanged fire with the militants, but no casualties were reported among the police as they stormed the insurgent hideout in the Mediterranean coastal city of el-Arish. The ministry said it found weapons, two explosive devices and two explosive belts. On Wednesday, Egyptian security officials said two separate explosive attacks overnight killed four policemen, a day after an ISIS suicide bomber killed four policemen and three civilians. Egypt has for years battled militants in Sinai.
