Members of the public assist firefighters at the scene of a blast in central Nairobi, Kenya on May 28, 2012.

Reuters reports ??A blast struck a shopping complex in Nairobi's business district during Monday's lunch hour, wounding more than a dozen people, but it was not immediately clear what had caused the explosion.?

Dense black smoke billowed from the badly damaged building and sirens blared as emergency service crews rushed to Moi Avenue, a major road running through the center of the Kenyan capital.

Police Commissioner Mathew Iteere said it was too early to determine the cause of the blast. He said blackened wires inside the trading center indicated a possible electrical fault but did not rule out a bomb.
