Talib Mutlaq Deewan and the estates of Himoud Saed Abtan, Usama Fadil Abbass and Oday Ismail Ibraheem sued Blackwater for its alleged culpability in the September 16, 2007 firefight in Nisoor Square in Baghdad in which as many as 17 civilians, including Abtan, Abbass and Ibraheem, were killed and as many as 22, including Deewan, were injured. The lawsuit alleged Blackwater violated the federal Alien Tort Statute in committing extrajudicial killing and war crimes, and that the company was liable for assault and battery, wrongful death, intentional and negligent infliction of emotional distress, and negligent hiring, training and supervision. This and six other lawsuits alleging abuses by Blackwater in Iraq were settled in January 2010. The terms of the settlement are confidential.
