Known as the White Widow, she is identified as Samantha Lewthwaite, a Muslim convert and daughter of a British military officer. She is named as leader of the terrorist assault on Nairobi’s exclusive Westgate mall now it its third day. Lewthwaite is the widow of the al Qaeda bomber Jermaine Lindsay who blew himself up in the July 7,2005 attacks on the London transport system, killing 26 people. She is said to have moved to Somalia in recent years and joined the al Qaeda-linked Al Shabaab movement. Prime Minister Cameron is cutting short a visit to the Balmoral royal residence to chair an emergency meeting. At least three Britons were reported among the fatalities of the mall attack.
