Bomb blast on CCTV: Explosion at Cairo security HQ captured on camera

Subscribe to ITN News: http://goo.gl/zRYiYn CCTV footage shows the moment a suicide car bomb exploded outside the Cairo Security Headquarters in the early hours of Friday morning, killing at least four people. Two more explosions went off in Cairo on Friday, one in the Dokki district which killed one person and another near a cinema on the road to the Pyramids of Giza which also led to one fatality. The violence, which comes on the third anniversary of the uprising that deposed of Hosni Mubarak, underscores the struggle of authorities to tame an insurgency which has been gaining pace since the army toppled Islamist President Mohamed Mursi in July.
