London attack: Khalid Masood identified as killer

Police have identified Khalid Masood as the man who carried out the Westminster attack, as the death toll rose to five. Masood, 52, was born as Adrian Elms in Kent and was shot dead by police. He had not been the subject of any current police investigations. PC Keith Palmer, 48, Aysha Frade and US tourist Kurt Cochran, 54, were killed on Wednesday, while a 75-year-old man died on Thursday evening. The so-called Islamic State group has said it was behind the attack. Three women and five men were arrested in London and Birmingham on suspicion of preparation of terrorist acts following Wednesday's attack. Home Secretary Amber Rudd told those gathered for a candlelit vigil in London's Trafalgar Square on Thursday evening that terrorists "will not win". "We are all connected and today we showed that by coming together, by going to work, by getting about our normal business, because the terrorists will not defeat us. We will defeat them," she said. Masood drove into pedestrians on Westminster Bridge before crashing his car into railings and then running into the grounds of Parliament, armed with a knife. He stabbed PC Palmer before being shot dead. The Metropolitan Police said there had been no prior intelligence about Masood's intention to carry out an attack. But he was known to the police and his previous convictions included causing grievous bodily harm, possession of offensive weapons and public order offences.
