Egypt ? The slain terror leader Abu Musab al-Zarqawi purportedly believed that Iraq’s Shiite Muslims were more dangerous than U.S. forces and more evil than dictator Saddam Hussein, according to a posthumous interview published Friday on the Internet.

The 33-page interview, conducted sometime before a U.S. fighter bomber killed the former al-Qaida in Iraq leader in June, could not be immediately authenticated. It was posted on a Web site known to be a clearinghouse for al-Qaida material.

The posting said the interview had been kept in al-Qaida’s archive but did not explain why the terror group had decided to release it six months after his death.

In the interview, al-Zarqawi is quoted as saying the leader of Iraq’s Shiites, Grand Ayatollah Ali al-Sistani, is a “satan” who publicly tells Shiites to stay above the violence but secretly tells them to attack.

“Al-Sistani has ordered his followers not to fight the Americans … and yet they hit Sunnis with assassinations, forcing them to flee their homes and attacking their mosques,” said al-Zarqawi, a Sunni from Jordan. “For us, the Shiites are far more dangerous than the Americans.”
