Islamist Shebab fighters are claiming to still be holding hostages inside a Nairobi shopping mall, as they continued to battle special forces on the fourth day of a deadly siege.
Sporadic shooting at the Westgate mall broke out again at dawn, hours after officials had claimed Kenyan troops were in "control" of the sprawling complex.

At least 62 people have been killed and close to 200 wounded in the siege, but concerns are high that the toll may yet rise.
Security sources said "one or two" militants were barricaded in or around a casino on one of the upper floors of the complex.
Meanwhile speculation is growing that a British woman nicknamed "the white widow" is among the attackers.
Samantha Lewthwaite, is the daughter of a British soldier and widow of suicide bomber Germaine Lindsay, who blew himself up on a London Underground train on July 7, 2005, killing 26 people.
