Our correspondent reported that the car was booby-trapped.

Quoting witnesses, the correspondent said 10 people were killed and scores wounded.

 

An occupation official however said six Iraqis and a US soldier were killed, the correspondent added.

 

"There were Iraqi civilians that were killed that were waiting in line," Colonel John Murray told reporters on Thursday, adding that the bomb had "very seriously wounded" at least three US soldiers.

 

The explosion left several cars ablaze at the entrance to the sprawling headquarters of the US-led occupation in Iraq, according to witnesses.

  

"We saw a car on fire. We think it was a car bomb. There were two bodies covered in sheets," said Muhammad Talum, who lives close to the 14th of July Bridge, the entrance to the heavily-fortified headquarters, nicknamed the Green Zone.

Soldiers in armoured humvees and police roped off the area as the inferno belched black smoke.

  

The powerful blast rattled windows in the neighbouring eastern Karrada neighborhood.

  

The last major car bomb in Baghdad hit the Mount Lebanon Hotel in mid-March.
