Forty-three years ago this month, the Munich Massacre shocked the world.

It was "the very first time that a terror attack was reported and broadcast, in real time, across the globe," reported in an August 2013 retrospective.

During the 1972 Munich Summer Olympics, 17 people died in connection with the massacre: 11 Israeli athletes, coaches and officials, a West German policeman and five members of the Palestinian terrorist group Black September.
