Arabic TV station Al-Jazeera has broadcast a videotape showing what it says is an American contractor of Lebanese origin held hostage in Iraq. The balding, middle-aged man was shown carrying a US passport and an identification card in the name of Dean Sadek. He was sitting in front of a green wall. Al-Jazeera did not air any audio but quoted Sadek as saying all businesses should stop cooperating with US authorities. The Qatar-based television said the kidnapping was claimed in the name of the 1920 Revolution Brigade, a known insurgent group. The name refers to the uprising against the British after World War I. It's not immediately clear when or where Sadek was kidnapped.
