Kenya calls for UK woman Samantha Lewthwaite's arrest

Interpol has issued a wanted persons notice for 29-year-old Briton Samantha Lewthwaite, after a request from Kenya.

Ms Lewthwaite, the widow of one of the four suicide bombers who attacked London on 7 July 2005, has been linked with Somali militant Islamist group al-Shabab.

Interpol did not link the warrant to the Nairobi shopping complex attack that left at least 67 dead.

Kenya is continuing three days of official mourning for the civilian and military victims of the siege, as funerals are held across the country.
