Scotland Yard announced Friday that the terrorist they identified as Khalid Masood was born Adrian Russell Ajao. His mother was a white British Christian living in southeast England. Officials said Ajao changed his name and moved to the Birmingham area after becoming involved in crime in his teens. The death toll of his murderous rampage in Westminster rose to four overnight when a man named as Leslie Rhodes, 75, from South London succumbed to his injuries. Counterterror raids continued early Friday with two more arrests—bringing the total to nine—in association with Wednesday’s attack.
