Turns out reports of that were BS but people still cling to this myth. I also recall stories of Iraqi ships were supposed to be loaded with the WMD sailing the ocean blue in circles.
In any case here is an article: No, Syria Doesn’t Have Saddam’s Chemical Weapons
http://www.wired.com/2012/07/syria-iraq-wmd-meme/
Interesting article, but it doesn’t debunk the Iraqi WMD meme. It’s a lot of conjecture (well thought out perhaps) with no evidence debunking anything.
Now Syria raises the spectre of chemical weapons
Israel and Hezbollah Keep Up Attacks
"The Israeli military said its targets included a convoy of trucks carrying weapons into Lebanon's Bekaa Valley from Syria "
Saddam Hussein had WMD after all
"Saddam Hussein certainly had WMD many years before Operation Iraqi Freedom. "
"To make the case for war in 2002 and 2003, General Colin Powell and others told the United Nations Security Council that the US Air Force had evidence of an active chemical-biological warfare program in Iraq. Among other things, Powell showed the UN diagrams of mobile laboratories, built into truck trailers, for mixing chemical and biological weapons in the field. (You cannot mix chemical or biological WMD in advance. You must mix them fresh and use them right away, or they are useless.)"
"If you go back to January through March of 2003, we had intelligence in the Defense Department that the Russians helped move, by convoy, a lot of the chemical and biological weapons into two locations in Syria and one in the Bekaa Valley in Lebanon. We think Russia and Iran have enhanced their inventory. The vast majority of those chemical and biological weapons were from Iraq "
"Iraqi Gen. Georges Sada published a book entitled "Saddam's Secrets" (2005-06) saying that there were 56 flights by large aircraft (civilian converted to cargo) from Iraq to Syria carrying WMDs, and also ground convoys of trucks just before the invasion. Syrian journalist Nizar Nayouf pinpointed locations in Syria of WMD storage areas. "
