This sort of reminds me of the MEMRI moment a while back (see my post from 2006), when a story how Ahmadinejad (Iranian president) called on the destruction of Israel. It was later revealed that this was an erroneous claim at best, as an Israeli run translational service mis-translated the speech.
But to the current story. A few days ago Venezuelan presidenet Hugo Chavez blamed the US for the earthquake in Haiti using its geo-weapon. This has been repeated throughout the web and print media ever since. Monthly review reports that this claim was falsely attributed to the Venezuelan president, saying the claim came from an obscure opinion post on a Venezuelan state TV.
