LAUSANNE, Switzerland — The international boxing association says it is developing a new anti-betting education program after three boxers were sanctioned by the IOC for gambling on fights at the Rio de Janeiro Olympics.

AIBA President C.K. Wu says “the actions of a very small minority at Rio 2016 have shown that what we believed to be a very clear message still needs some reinforcing.”

Olympic boxers Michael Conlan and Steve Donnelly of Ireland and Britain’s Antony Fowler received “severe reprimands” from the International Olympic Committee on Wednesday for betting on fights during the Rio Games.

Wu says AIBA is developing “a clear and comprehensive educational program” for 200 national federations and their boxers.

He says an AIBA disciplinary commission will deal with three boxers reprimanded by the IOC.
