Jane Fonda, the celebrated Hollywood actress who led demonstrations against the Vietnam war, is returning to her anti-war activities by calling the US to end military operations in Iraq.

Fonda announced over the weekend that she would be leading a cross-country drive in a bio-diesel bus to call for an end to US military operations in Iraq.

She said the campaign would include her family and the families of Iraq war veterans and casualties. Fonda said she decided to resume her anti-war activities at the urging of war veterans.

"I've decided I'm coming out," she said. "I have not taken a stand on any war since Vietnam," she said. "I carry a lot of baggage from that."

Fonda incited controversy in July 1972 when she was photographed sitting on a North Vietnamese anti-aircraft gun while on a tour of the country to drum up support to end the war. She has since apologised for her actions.
