President George W Bush was heckled inside the Australian parliament and jeered by protesters outside as he defended the invasion of Iraq and the war on terror

Security guards removed the 18-year-old son of Mamdouh Habib, one of two Australians held at a Camp X-Ray in Cuba for two years without charge after the Afghan invasion.

He was dragged out, arms pinned behind his back, after yelling: "Hey Bush, what about my Dad?"

The chamber was packed with well-known Australians, including celebrity Crocodile Hunter Steve Irwin in his trademark khaki shorts and tennis star Lleyton Hewitt.

Meanwhile, outside, a crowd of up to 2,000 protesters chanted anti-US slogans and waved banners reading: "Yankee Go Home" and "US Sucks".

An Osama bin Laden lookalike weaved through the crowd carrying a placard reading "Come and Get Me", and there were two activists dressed as Saddam Hussein and President Bush holding hands.
