Nerve Gas or Smokescreen?

Novinite is reporting that US troops used nerve gas in capturing Saddam. They cite ITAR-TASS, which in turn quotes “Saudi press”. I can’t find any relevant references on news.google, so my question is this: has this report been substantiated anywhere else? Also, can someone who speaks Russian dig up the original story from ITAR-TASS? Their English-language page appears to be down.
