The United States confirmed today that al-Zubaydi died at a U.S. military hospital in Iraq on 2 December. He was 67.
The U.S. military had stated on 3 December that an individual had died in its custody, but did not refer to al-Zubaydi by name. His identity only became clear on 5 December when Saddam's half-brother, a co-defendant in his trial, revealed al-Zubaydi's death during a courtroom complaint about what he said were poor medical facilities for detainees.
The cause of al-Zubaydi's death remains unclear.
He was prime minister for two years in the early 1990s, and had been on the United States’ most-wanted list when the U.S.-led coalition invaded Iraq in 2003.
