A gun battle inside a shopping centre in the Kenyan capital Nairobi has left dozens of people dead, Kenyan officials say.
The gunmen attacked Westgate centre - one of the city's most exclusive shopping malls.
The BBC's Anne Soy reported from outside the mall, as military armoured vehicles move towards the building.
