The Kenyan military says it has rescued most of the hostages from the shopping centre that was stormed Islamist militants at the weekend.

But the BBC's Komla Dumor at the scene in Nairobi says that between 10 and 15 attackers - thought to be militants from the Somali al-Shabab movement - are still inside the Westgate shopping centre.

At least 68 people have been killed and more than 170 injured since the attack began on Saturday.
