Interesting movie about sultan, a harem and female slave

[wositelec]

I am looking for a movie in style "Lawrence of Arabia". It was similar in plot to the book "White Gold" by Gill Miles. The soldiers bring a white blonde haired woman (female archeologist, because she has similar blouse) before the Sultan's throne with other people as white slaves. They rip open her blouse and show her breasts. Above the other kneelers, they hold metal wedges over their heads and hammers to crush their skulls at the Sultan's command, but they don't do it. I think the film was old (60's or 70's), perhaps it could be made in United States.

I think that it was adventure movie from 60s or 70s. It isn't "Ilsa, Harem Keeper of the Oil Sheiks" (1976) I think that scene was violent. It was about white slaves trading.
