A teenage Canadian member of the Khadr family has been designated an "enemy combatant" and an al Qaeda fighter at a military tribunal held in Guantanamo Bay, Cuba.

Omar Khadr, 17, is accused of killing an American soldier, planting mines to target U.S. convoys, and gathering surveillance at an airport in Afghanistan, according to U.S. Defence Department documents unclassified and released Thursday.

Most of the evidence at the hearing was considered classified and only a one-page summary of the allegations was released.

Khadr's Canadian lawyers were not present at the Sept. 8 tribunal and have not been able to contact the teen.

They recently wrote him a letter advising he not appear before any tribunal without legal representation. Khadr boycotted the hearing.

Foreign Affairs spokesperson Rodney Moore said Thursday that Canada has formally requested that the U.S. government allow a Canadian lawyer to visit Omar.

Khadr's older brother, Abdurahman Khadr, 21, told the Toronto Star that his family just wants Omar tried in a court, not at a tribunal.

The Khadr family has been the focus of much media attention since Abdurahman was released from Guantanamo Bay last year.

He claimed U.S. authorities took all of his travel documents and dropped him off in Afghanistan to fend for himself. Months later however, he said he lied and was working as an undercover agent for the CIA.

Their father, Ahmed Khadr, 57, was accused of being an al Qaeda financier with close ties to Osama bin Laden. He died in a gun battle with coalition forces near Afghanistan last October.

Abdurahman has admitted attending a training camp in Afghanistan. His younger brother, Karim, 14, also spent time at Guantanamo Bay.

Khadr's mother, Elsamnah, and sister Zaynab, have been placed on a passport control list for repeatedly losing their passports and requesting replacements.
