MR NDLOVU
When we heard the throwing of stones as well as the shooting, I heard one voice shouting, ordering that we lie down.  Indeed we lied down and some of us against the shack.  And the shooting continued, and the throwing of stones did not stop.  And we later on heard this very big explosion which was different from the initial gunshots.  And when I looked around I saw this ball of green fire directed towards the other group.  And this explosion happened again.  I tried to look around to establish where it came from, and it transpired that this explosion came from our group.  And I ultimately identified the person who was shooting from our direction, from our group rather.
