Yeah, macman104: I'd heard about that back then as well. It seems to me that mentioning white phosphorous is something of an internet meme -- they might be weapons, or someone might have been accidentally hit with tracer fire, so in a way, it might be a chemical attack, or it might be a coincidence, but since people might have casual phosphors exposure, like mir: it just generates excitement for it's own sake. This was definitely the case, back in 2004, sci.chem was constantly mentioning white phosphorus, trying to determine it's contents in shells -- based on blast-burn radius or some such foo, even after the US admitted it. That's where I get the meme label for these sorts of stories -- an idea, that propagates, not because it has info on it's own, or leads to other info, but instead exists because it's exciting, just by mentioning it.
