Gunmen have opened fire inside a shopping centre in Kenya.
Bursts of gunfire were heard from outside the shopping centre in Nairobi, where cars were left abandoned.
Witnesses said half a dozen grenades also went off along with sounds of AK-47 gunfire.
Nairobi police chief Benson Kibue said that gunmen besieged the building. He said officers are on the ground and are engaging the attackers.
He said the men were trying to rob a shop within the centre when the shoot-out began.
Five dozen people rushed out from the mall as the gunfire and grenade attacks continued.
