At least 100 fighters sneaked into Kirkuk in the early hours of Friday with machine guns, rocket propelled grenades, suicide vests and a message: 'Islamic State has taken over.' The message blared out from several mosque loudspeakers while the militants went on a rampage. By the time they had blasted their way across the city in a brazen and complex attack, 99 civilians and members of the security forces were dead and 63 of their own were in the morgue, according to Iraqi security officials.
