Palestinian terrorists who held two Fox News journalists hostage for almost two weeks threatened in an online message to abduct non-Muslims visiting the Palestinian territories and kill them unless their demands were met. The statement, posted Saturday in the name of the Holy Jihad Brigades on a Web site frequently used by militants, said the group would kill any hostages it takes unless they converted to Islam, paid a ransom or Muslim prisoners were exchanged for their release. "Any infidel blood will have no sanctity," the group said in a new Web statement. Either Islam, death or something given in return, the group added, apparently referring to a ransom or a swap for prisoners. It was not possible to verify the authenticity of Saturday's statement, which was dated August 27 -the day terrorists released American journalist Steve Centanni, 60, and cameraman Olaf Wiig, 36, of New Zealand. They were seized Aug. 14 in Gaza City.
