A meme being shared on Facebook claims to show that Iraqi WMDs have been found in Syria. However the photo shows US chemical weapons in a depot in Utah, in the USA.
The use of this image in a misleading way is not new, it was also used to illustrate a story about claims of chemical weapons being found in Libya:
Over the last few years there have been several claims about WMDs (generally chemical weapons) being moved out of Iraq, including to Syria. While it has not been ruled out, there's no solid evidence as to what happened. And no Iraqi chemical weapons are known to have been found in Syria.
ISG formed a special working group to investigate and consider these claims. Charles Duelfer, head of inspectorate at time of publication, summarized the group's conclusion: "Based on the evidence available at present, ISG judged that it was unlikely that an official transfer of WMD material from Iraq to Syria took place. However, ISG was unable to rule out unofficial movement of limited WMD-related materials."
And if you doubt even the NYTimes provenance, note that the pallets are marked "105 MM M360", which is a US shell. The Shells themselves are marked "GB GAS - 105MM CARTRIDGE". GB Gas is another term for Sarin (the term GB just means "German nerve agent B").
