Fonda regrets visit to Vietnam gun site

Actress Jane Fonda has expressed regret at visiting a North Vietnamese gun site in 1972.

The Barbarella star earned the nickname 'Hanoi Jane' from the controversial trip but years later, Fonda admits the visit to the anti-aircraft gun site used to shoot down US pilots was a "betrayal" of America's military.

She says in an upcoming 60 Minutes interview: "The image of Jane Fonda, Barbarella, Henry Fonda's daughter… sitting on an enemy aircraft gun was a betrayal. (It was) the largest lapse of judgment that I can even imagine."

But she said she did not regret visiting Hanoi, or being photographed with American prisoners of war there.

She added:, "There are hundreds of American delegations that had met with the POWs. Both sides were using the POWs for propaganda… It's not something that I will apologise for."

Fonda was one of many Americans who strongly opposed the Vietnam war.
