Report: "White Widow" Key Figure in Al-Shabab

Somali-based Al Qaeda-linked group claimed responsibility for the recent mall attack in Nairobi

Sky News has obtained a Kenyan intelligence report which for the first time shows the reach of the al Shabaab terror network - which carried out the Nairobi shopping mall attack - and the extent of British involvement within the group.

It suggests that Samantha Lewthwaite - the British woman known as the 'White Widow' because she was married to one of the 7/7 London bombers - is an important figure in the terror outfit, plotting multiple bomb attacks across Kenya.

Sky has also been given access to a personal diary of hers which gives a fascinating insight into her mind, where she talks about her ambitions for her children and her love for her husband.
