In a recently released report, the United Nations Committee Against Torture urges Canada to immediately sign the transfer papers to bring the convicted terrorist and murderer back to his country of birth.

"The Committee urges the State party to promptly approve Omar Khadr's transfer application and to ensure that he receives appropriate redress for human rights violations that the Canadian Supreme Court has ruled he experienced," the committee wrote.

The members do not define what they mean by "appropriate redress" in Khadr's case. It calls Canada "complicit" in violating Khadr's human rights, as was ruled by the Supreme Court.

Khadr has been held in Guantanamo Bay, Cuba, since he threw a grenade and killed US medic Sergeant First Class Christopher Speer in Afghanistan in 2002.

During his trial, Khadr also admitted to terrorism.

The UN group also took Canada to task over the treatment of Canadian citizens Abdullah Almalki, Ahmad Abou Elmaati and Muayyed Nureddin, who were held in prisons in Syria and Egypt.

The panel said they should "receive redress, including adequate compensation and rehabilitation."

The Iacobucci Inquiry ruled their cases were similar to that of Maher Arar, who was held in a Syrian prison and tortured. Arar was compensated with $10 million and got an apology from Prime Minister Stephen Harper in 2007.

The UN committee is made up of 10 people of "high moral character and recognized competence in the field of human rights."

Their countries of origin include, among others, the US, China, Senegal, Georgia and Morocco.
