A razor wire was erected on the border between South Africa and Ciskei to prevent the marchers from entering Bisho. When Kasrils led a group trying to break through the Ciskei Defence Force lines to enter Bisho, Ciskei Defence Force soldiers opened fire on the marchers with automatic weapons, killing 28 marchers and one soldier, and injuring over 200. More than 425 rounds were fired, the first fusillade lasting one and a half minutes, and the second lasting a minute.
