Egyptian police killed eight Hasm members in a shootout during a raid on their training camp south of Cairo, the interior ministry said on Sunday. The National Security Agency was able to discover a hideout used by the group in a desert area in Fayoum, to train "new youths elements" on the use of arms, the ministry said in a statement. The ministry said they shot at police as they attempted to apprehend them. According to the statement, two other Hasm hideouts located in Giza and Sharqiya governorates were raided, and five members of the group arrested. Police found documents detailing upcoming terrorist operations at the two Hasm hideouts. Sunday's announcement comes only two days after the police said they had shot dead two Hasm leaders during a raid on their hiding place, also in Fayoum, which is around 100km south of Cairo. Hasm has claimed responsibility for a number of attacks against Egyptian security personnel in recent months, mostly targeting police checkpoints. Egyptian security forces have arrested and killed dozens of suspected Hasm members in the past few months. Egyptian officials have maintained that that the group is linked to the banned Muslim Brotherhood group.
