Kenyan security forces appear to have launched an assault on the Westgate shopping complex in the capital Nairobi in an attempt to break the siege there.

Heavy gunfire was heard at the complex and a huge cloud of smoke could be seen billowing from the building.

Sixty-nine people have been killed and more than 170 injured since the attack began in Kenya’s capital on Saturday.

About 10 attackers were thought to be inside. The Somali al-Shabab movement has said carried out the attack. Report by BBC
