hope its not a zero zero grenade:
"The Zero-Zero Handgrenade incident took place at approximately midnight on 15/26 June 1985. It was the culmination of an operation carried out by members of the Security Branch of the South African Police, including members of the C10 Unit (Vlakplaas) and members of the East Rand Division. The operation was the idea of and formulated by Johannes Velde van der Merwe (the 7th Applicant) who was then second in charge of the Security Branch. Approval for the execution of the operation was given by Louis Le Grange, the Minister of Police.
The operation entailed the infiltration of the Congress of South African Students (COSAS) members on the East Rand, providing them with handgrenades and a limpet mine of which the timing devices had been reduced to zero seconds and enticing them to use such explosive devices simultaneously. The operation resulted in the death of eight people and seven people being seriously injured....
They decided that their targets would be symbolic in nature. They decided on the deserted burnt out houses of Stephen and David Nomani, two persons who were suspected of being collaborators and who had been driven out of the area. The next night he and the other members of his group who were still prepared to participate each received a handgrenade from Mamasela and the 2nd Applicant. He was surprised to learn that Congress Mtsweni was going to target an electrical substation with a limpet mine. The witness then proceeded with his group to the house of Steve Nomani. His group consisted of himself, Samuel Lekatsa, Humphrey Tshabalala and Osborne Dlamini. At the house they performed the drill that they had been trained by "Mike" and "James". The witness counted one and they all held the lever of their handgrenade, he counted two and they all pulled the pin and as he counted three, the count on which they were all to throw their grenades at the house, the grenades exploded while in their hands."
