Omar Khadr in Saskatoon prison hospital after shoulder operation

Omar Khadr, the 27-year-old man who made headlines for years over his trial and imprisonment for war crimes, is being treated in a prison hospital in Saskatchewan, his lawyer says.

According to Dennis Edney, Khadr recently underwent treatment at the University of Alberta Hospital in Edmonton to correct a serious medical problems related to his shoulder. His lawyer said the shoulder problem was the result of injuries he received during a firefight in Afghanistan. 

According to Edney, Khadr needed an operation on his shoulder which included inserting a stent to help drain fluids.  

The man spent two weeks at University of Alberta Hospital. A few days ago, he was moved to the Regional Psychiatric Centre, a federal corrections facility in Saskatoon.  

His lawyer said the move had nothing to do with Khadr's psychiatric state. The facility was simply chosen because it was capable of providing for his medical needs in a secure environment. Khadr currently needs 24-hour-a-day medical attention. He is expected to be in hospital in Saskatoon for a month.

Khadr pleaded guilty in 2010 to five war crimes, including murder, for killing an American soldier in Afghanistan when he was 15.

The 27-year-old was being held at the federal maximum-security prison in Edmonton while serving the remainder of an eight-year sentence. Khadr was transferred to Canada from a U.S. military base in Guantanamo Bay in September 2012.
