Video footage and eye witness accounts from the scene of a brutal murder in London on Wednesday seem to indicate that the attackers may have been politically motivated. Counterterrorism officers are leading the investigation. Two men have been arrested.
Two men with butcher knives hacked another to death Wednesday near a London military barracks and one then went on video to explain the crime — shouting political statements, gesturing with bloodied hands and waving a meat cleaver. Soon after, arriving police shot and wounded the unidentified assailants and took them into custody.
