An American soldier blinded in Afghanistan and the widow of another soldier killed there are suing a Canadian citizen who was held at Guantanamo Bay and pleaded guilty to committing five war crimes when he was 15.

Layne Morris of Utah and Tabitha Speer of North Carolina filed their $44.7 million lawsuit in federal court in Utah on Friday.

The lawsuit cites a plea deal Omar Khadr signed in 2010 that he committed the crimes, including the killing of U.S. soldier Christopher Speer. Khadr is now in Canada, serving the remainder of his sentence.

Khadr is suing the Canadian government for $20 million, alleging wrongful imprisonment.

Khadr's attorney has said the facts of the plea deal are false and Khadr signed it so he could return to Canada.
