Militants Who Killed Over 300 At Egypt Mosque Brandished ISIS Flags

Yesterday, Egypt suffered its worst mass killing since at least 2013 – a massacre that was ironically carried out by the country’s security forces – when five armed gunmen stormed a mosque in northern Sinai and killed more than 300 people, including at least two dozen children.
And while no group has stepped up to take responsibility for the murderous rampage, Reuters reported that the attackers brandished an Islamic State flag, according to witness accounts. Prosecutors are already investigating the group.
