London: Interpol on Thursday issued an arrest notice on behalf of Kenyan authorities for Samantha Lewthwaite, the fugitive Briton whom news media have dubbed the "white widow".

Lewthwaite — a 29-year-old Muslim convert whose first husband was one of the suicide bombers in the 2005 attack on the London transit system that killed 52 commuters — is wanted by Kenyan authorities over alleged involvement in a plot to bomb holiday resorts there.

Social media reports that a white female was leading last week's terrorist attack on an upscale Nairobi shopping mall — followed by comments from Kenya's foreign minister that a British woman had been involved — led some British broadcasters and newspapers to link Lewthwaite to the recent attack on the Westgate mall, despite the lack of hard evidence that she was involved.

The Interpol notice made no mention of Westgate, however, saying that Lewthwaite is wanted on charges of possessing explosives and conspiracy to commit a felony in December 2011.
