A fire swept one of Nairobi's largest open-air markets early Thursday, killing 15 people and sending 70 injured to hospitals, an official said, according to AP. Nairobi County Commissioner Kangethe Thuku said six bodies had been recovered and nine were in a building and had yet to be retrieved. Rescue teams searched for more bodies and survivors in Gikomba market in the Pumwani low-income neighborhood in Kenya's capital. The cause of the fire was not immediately announced but "for now we have declared this site a crime scene," Thuku said. Security forces guarded the smoking scene as workers picked through the blackened rubble.
