KBR Inc and its Jordanian contractor are being sued for human trafficking by a Nepalese survivor and the families of 12 other employees who were killed while being transported, allegedly against their will, to work in a U.S. military base in Iraq...The lawsuit, filed on Wednesday, says military contractor KBR and Daoud & Partners recruited the men in Nepal by promising them jobs at a luxury hotel in Amman, Jordan, but instead sent them to Iraq where all but one were kidnapped and killed... KBR would not comment on the lawsuit, but said in a statement that its employees were expected to adhere to a company code of conduct and complete ethics training that includes information about human trafficking...Daoud, which provided food, construction and transportation services at U.S. bases in Iraq, could not be reached for comment.
