A suicide bomber has blown himself up in Karachi. The attack happened during a procession of Shia Muslims on their holiest day.
Mobs unleashed their anger after the blast, setting ablaze buildings, shops and cars, and attacked local police.
Paramilitary forces have since taken control of central Karachi, and officials are appealing for calm, but already 30 people are dead, and more than 80 others injured.
