CAIRO - An Egyptian Christian who promoted a film that has provoked protests in the region over its portrayal of Prophet Mohammad said on Wednesday he was sorry that US diplomats were killed and said Muslims who objected should do so peacefully.

Morris Sadek, speaking by phone from the United States where he lives, also told Reuters that his objective in backing the film was to highlight discrimination against Christians who make up about 10 percent of Egypt's 83 million people.

Asked if he felt sorry about the deaths, Sadek said: "Of course, of course, of course. Thought should be answered by thought," adding that he did not consider the film titled "Innocence of Muslims" as offensive to Islam.
