LONDON: Thirteen terrorists were killed in north Sinai in a security operation, the spokesman for the Egyptian armed forces said on Friday. Seven militants were killed during the raid and six were later killed after they tried to flee but were tracked to their hideout using cameras. The raid, carried out by the armed forces, took place after intelligence reports suggested that the terrorists were hiding out at a plantation in northern Sinai. The armed forces seized a four-wheel drive vehicle, a motorbike, 10 explosive devices, four explosive belts, several rifles and ammunition as well as various mobile phones and walkie-talkies during the operation. Security forces have been battling a long-running extremist insurgency in the Sinai Peninsula - in Egypt"s northeast - that is spearheaded by a local affiliate of Daesh.
