The family of 18-year-old London bomber Hasib Mir Hussain say they are "devastated" by what has happened. In a statement they described the bus bomber as "a loving and normal young man who gave us no concern". "We had no knowledge of his activities and had we done, we would have done everything in our power to stop him." Earlier, an Egyptian chemistry expert sought by police over the attacks, Magdi Mahmoud al-Nashar, 33, was arrested in Cairo. Hussain was reported missing by his family in the aftermath of the bombings. LONDON BOMBERS Shezhad Tanweer. Photo: Ross Parry Mohammad Sidique...
