In 2009, WJC officials called for the extradition Ukrainian-born John Demjanjuk from the United States to Germany, where he was wanted on charges of aiding to kill at least 27,900 Jews at the Sobibor death camp during World War II. Demjanjuk's trial and conviction by a Munich court in May 2011 was hailed by the organization. It declared: "Belatedly, justice has now been done, and the family members of those who were brutally murdered in Sobibor will certainly welcome this verdict."
