It didn't kill them because they were out of the fragmentation area. Tell me, if someone threw a grenade, would you see a flash? Yes. If you were close enough, you'd see a white flash (or another color, I suppose. It depends on the materials used to make the grenade) and perhaps not be killed, but you'd be blinded for a few seconds. I believe this is called 'eye flash.' The same thing happens if you try to weld without a welding mask. Your pupils become smaller as light becomes greater, so you don't let in as much light. If it's dark, your pupils are big. This is to let more light in. If you were to let too much light in while your pupils were big, it would burn your retina, causing temporary blindness.
