London Terror Investigation Traces Long Path to Radicalization, Via Somalia

More than a week after a British soldier was killed in broad daylight on a London street, in an apparent Islamist-motivated attack, one of the suspects has been charged with murder. The other is still recovering in a hospital after being shot by police. Authorities are trying to piece together how two British citizens, who were both known to security services, allegedly went on to commit such a brutal attack. Henry Ridgwell reports from London.
