The White House beat a strategic retreat last week on its ideas for a new multiagency interrogation unit, giving its task force another two months to come up with a plan everybody can live with.

But if initial reactions are any guide, the White House faces an uphill fight in creating an organization that can satisfy military, intelligence and law enforcement needs at once.

"A sobbing Canadian teenager begged for help as he was interrogated at the US 'war on terror' camp at Guantanamo Bay, Cuba, in the very first video glimpse of any such questioning released on Tuesday," AFP reports.

The video was posted online by attorneys for terror suspect Omar Khadr, who is shown being questioned at the prison by Canadian Security Intelligence Service (CSIS) agents in February, 2003. He was 16 years old.

Khadr, accused of killing a US soldier in a firefight in Afghanistan, has been held at Gitmo since his arrest in 2002, when he was 15 years old.

"Help me, help me, help me," Khadr says in the video, weeping, holding his head in his hands.
