At least six people are dead and roughly 50 wounded after a car bomb tore through the main Egyptian police headquarters in Cairo Friday. Hours after the initial attack came two other explosions, one targeting police vehicles and another a police center. The outburst falls just one day before the anniversary of the 2011 revolt, which led to the toppling of former President Hosni Mubarak. As of Friday morning, no one had claimed responsibility for the attack.
