Toronto ? A judge on Friday denied bail for a Canadian wanted by the United States for supplying al-Qaida with weapons, saying his alleged terrorist links make him a flight risk.

Abdullah Khadr, 24, has been charged in the United States with conspiracy to murder Americans abroad and possession of a destructive device. He is being held in Canada on an extradition warrant.

Authorities say Khadr confessed during questioning, but his attorney argues the confessions were derived by torture after he was detained without charge in Pakistan in October 2004.

Prosecutors say Khadr, son of purported al-Qaida financier and Osama bin Laden friend Ahmed Said Khadr, bought AK-47 and mortar rounds, rocket-propelled grenades and containers of mine components for al-Qaida to use against coalition forces in Afghanistan.

The weapons purchases were reportedly made at the request of his Egyptian-born Canadian father, who was killed in 2003 when a Pakistani helicopter fired on a house where he was staying with other senior al-Qaida operatives, authorities said.
