Emblems of the International Red Cross and Red Crescent Movement with Sun and the Red Crystal, are defined in the Geneva Conventions and their Additional Protocols as symbols for protective use. When used as an organizational logo, these symbols only indicate that persons, vehicles, buildings, etc. which bear the symbols belong to a specific organization which is part of the International Red Cross and Red Crescent Movement (like the ICRC, the International Federation or the national Red Cross and Red Crescent societies).
