The last Westerner held in the US prison for terror suspects in Guantanamo Bay, who was arrested as a teen in Afghanistan, returned to his native Canada yesterday, a Canadian cabinet minister and the Pentagon said.

Omar Khadr, now 26, left the prison in Cuba on a US military plane and arrived at a Canadian air base in Trenton in Ontario province at 1.40pm, said Public SafetyMinister Vic Toews.

Khadr was sent to the Millhaven maximum security prison Bath, Ontario, the minister said in a statement he read to reporters.

“Omar Khadr is a known supporter of the Al-Qaeda terrorist network and a convicted terrorist,” Toews said.

The Pentagon confirmed the transfer but gave few details. It said 166 inmates remain in Guantanamo.

Born in Toronto in 1986 to a family of militants, Khadr was 15 when he was wounded and captured by US troops in 2002 duringa four-hour US ground and air attack in Afghanistan.

Khadr, the youngest detainee ever held at the US naval facility in Guantanamo Bay, filed a formal transfer request with US authorities in November.

Now a tall man with a heavy beard and a scarred face, Khadr has been eligible for a transfer to Canada since October 2011 after pleading guilty in 2010 to five war crimes, including for throwing the grenadethat claimed the life of US soldierChristopher Speer.

Both Ottawa and Washington had approved his plea deal, but a final nod was delayed as Ottawa and Washington bickered over details.

The Khadr family went to Pakistan when Omar was a child to help with reconstruction along the Pakistan-Afghan border following the withdrawal of Russian troops, according to an online family biography.

After 1996, the family lived in a compound in Jalalabad, Afghanistan, where young Khadr allegedly met the late Al-Qaeda terror network chief Osama bin Laden.
