I am confident that Ibrahim Hooper is flying to Baghdad this very minute in order to explain to the Zarqawi group that Islam actually forbids this sort of thing. Islamic Tolerance Alert from Iraq: "Iraq: Al-Zarqawi Group Boasts Killing Christian," from [1] AKI, :

Baghdad, 7 April (AKI) The Mujahadeen Council, a leading insurgency group linked to al-Qaeda in Iraq, has announced the killing of a Christian in Mosul "for offending the prophet Mohammed." In a statement posted to the Internet, the group, whose military arm is still headed by Jordanian militant Abu Musab al-Zarqawi, said that on Tuesday it "eliminated" a Christian in Mosul. "We eliminated him, because this impure crusader offended our noble prophet Mohammed. We killed him in the al-Tahir quarter of Mosul" it read.
