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.

Soon after, arriving police shot and wounded the unidentified assailants and took them into custody.
