Fresh violence in Iraq today left 16 Iraqis dead amid pro-Saddam riots, and attacks on US forces injured three soldiers.
Saddam Hussein was being held by US forces at a secret location for interrogation ahead of a trial in the months ahead. He could face the death penalty.
In Saddam's home town Tikrit, one of several Sunni Muslim cities where his supporters have vented rage at his capture on Saturday, a roadside bomb wounded three US soldiers today.
The US military said troops killed 11 Saddam loyalists who tried to ambush them in Samarra, north of Baghdad, last night.
The cities of Falluja and nearby Ramadi also saw pro-Saddam riots overnight. US troops said they came under fire in a spate of attacks and killed five Iraqis. Witnesses said hundreds of people stormed the US-appointed mayor's office in Falluja.
The attacks came in the heartland of Saddam support north and west of Baghdad, home to the Sunni minority that has long dominated Iraq.
U.S. President George W. Bush, whose boosted re-election prospects were reflected in opinion polls , warned yesterday that "terrorists in Iraq remain dangerous".
