Kano, the largest city in Nigeria's Muslim north, is an ancient, sprawling city of more than 9 million. Last Friday, the Muslim day of prayers was shattered by a series of coordinated bomb blasts.
Just down the street from one of the main market areas in the city, the street remains blocked off from a police station hit in the attacks. The radical Islamist sect Boko Haram claimed responsibility.
Sagir Ali, a security guard at a parking lot at the market, says he watched as nearby government offices were attacked.
