A public talk by Dr. Riyadh Lafta of Baghdad’s Al-Mustansiriya University College scheduled for Friday, April 20, 2007 at Simon Fraser University’s Morris J. Wosk Centre for Dialogue, in Vancouver, has been cancelled. American and British authorities denied him a visit visa. Alternative arrangements at the University of Washington (U of W) in Seattle have been made for a talk by Dr. Les Roberts, co-author with Dr. Lafta of a Lancet article on Iraqi deaths published in October 2006. The study estimated 654,965 persons have died as a consequence of the occupation. Of these, 601,027 have died from violence. The event in Vancouver was moderated by Dr. Tim Takaro, who is studying the rise in childhood cancer in Iraq with Dr. Lafta and researchers from the U of W.
