Six dead and dozens hurt in Istanbul blast

A bomb killed six passers-by in a bustling pedestrian shopping avenue in Istanbul on Sunday, hurting dozens more. Footage taken by nearby security cameras shows the blast originated in a bag or case left by a bench.

Turkish President Recep Tayyip Erdogan called the blast a "treacherous attack" and said its perpetrators would be punished. He did not say who was behind the attack but said it had the "smell of terror" without offering details and also adding that was not certain yet.
