The father of Nicholas Berg, the kidnapped U.S. contractor who was believed to have been beheaded by Abu Musab al-Zarqawi in Iraq, said Thursday that he doesn't see any good coming from al-Zarqawi's death.

"I think the news of the loss of any human being is a tragedy. I think al-Zarqawi's death is a double tragedy" he said. "His death will incite a new wave of revenge. George Bush and al-Zarqawi are two men who believe in revenge."
