Egyptian authorities prevented an attack with a home-made bomb in Giza intended to target a security patrol on Friday, Reuters reports. There was no immediate claim of responsibility for the intended attack, but the Interior Ministry attributed it to the Ikhwan. Two policemen and three civilians reportedly suffered minor injuries when the device exploded during the attempt to defuse it. Seven terrorists and 15 members of the military died during clashes in North Sinai one day later, according to an Armed Forces statement. The Islamic State has claimed responsibility for the attack, saying it killed 20 Egyptian troops, reports Reuters.
