A Kenya police helicopter patrols over buildings surrounding the Westgate shopping centre during an exchange of gunfire inside the mall in Nairobi September 23, 2013. Thick smoke poured from the besieged Nairobi mall where Kenyan officials said their forces were closing in on Islamists holding hostages on Monday, three days after a raid by Somalia's al Shabaab killed at least 62 people. It remained unclear how many gunmen and hostages were still cornered in the Westgate shopping centre, two hours after a series of loud explosions and gunfire were followed by a plume of black smoke, that grew in volume from one part of the complex.
