An Egyptian actor turned violent live on a Candid Camera-type show after he was told that he was being interviewed for an Israeli TV channel.
Ayman Kandeel flew into a rage and assaulted the female presenters Iman Mubarak and the male "producer" Amr 'Alaa in a wind-up that went wrong.
The stunt, played out in a cross between Punk'd and Candid Camera, strives to find out how Egyptian celebrities, having originally been promised that they are appearing on German television, react when they are told that the programme is actually being aired in Israel.
During the interview, Kandeel becomes becoming increasingly suspicious and annoyed by some of the questions he is asked. Then the show's "producer" takes to the floor, introduces himself as an Israeli and accuses Kandeel of anti-Semitism.
Kandeel - who claimed to have a gun earlier in the programme - loses his temper and attacks the producer. He then hits the female interviewer across the face and pushes her to the ground.
As things spiral out of control, an increasingly anxious production crew try to calm things down by telling him that he is thye victim of a televised prank.
He is later shown hugging the female interviewer a hug and saying "you brought it upon yourself" to applause from the audience.
Another victim of the mock show, actress Mayer el-Beblawi, launched into a violent anti-Semitic diatribe when informed she was on the fake Israeli show.
"In that country [Israel] they are all liars," she said. "They keep whining all the time about the Holocaust, or whatever it's called.
"These people sawed off [the head] of John the Baptist. They are the slayers of the prophets. What else can we say about them? Allah did not curse the worm and moth as much as he cursed the Jews."
