5 killed and 2 wounded in Philadelphia as man randomly opens fire

Five people have been killed and two children wounded after a man wearing a bullet-proof vest opened fire in the US city of Philadelphia. The suspected attacker, a 40-year-old man who is now in custody, was carrying an AR-15-style rifle, a handgun, a police scanner and ammunition. He has no known connection to the victims and, with no clear motive, the shooting appeared to be random.
