Nicholas Berg

Nicholas Evan Berg was an American freelance radio-tower repairman who went to Iraq after the United States' invasion of Iraq. He was abducted and beheaded according to a video released in May 2004 by Islamist militants in response to the Abu Ghraib torture and prisoner abuse involving the United States Army and Iraqi prisoners. The CIA claimed Berg was murdered by Abu Musab al-Zarqawi. The decapitation video was released on the internet, reportedly from London to a Malaysian-hosted homepage by the Islamist organization Jama'at al-Tawhid wal-Jihad.
