Who is the White Widow?

Widow of one of the 2005 London bombers, linked by authorities to Al Shabaab

International police body Interpol has issued its highest level wanted persons notice on behalf of Kenyan authorities for Briton Samantha Lewthwaite, known as the 'white widow'.

Ms Lewthwaite is the widow of one of the four suicide bombers who attacked London on 7 July 2005 and has been linked with the Somali militant Islamist group al-Shabab—the organisation behind the attack on Nairobi's Westgate shopping mall.
