A British lawmaker tried to help save the life of a policeman who was fatally stabbed during Wednesday’s attack outside the United Kingdom’s Houses of Parliament in London.

Tobias Ellwood, a member of Parliament and British foreign minister for the Middle East and Africa, rushed to the side of officer Keith Palmer, attempting to give him CPR and to stop the blood flowing from his wound by applying pressure, according to the Telegraph.
