At least 15 people were killed and 147 hurt by two suicide vehicle bombs in the former rebel bastion of Fallujah on Thursday, an interior ministry official said. Earlier, a defence ministry official said at least 10 people were killed in the bombings, which he said targeted Ira More..qi police posts.
Policemen were among the wounded in the near simultaneous blasts, which damaged police posts in western and eastern Fallujah, the defence ministry official said.
A media correspondent said several bodies were left splayed out on the ground. A curfew was imposed in the two districts immediately after the blasts.
Police officer Omar Mohammed said: "Al-Golan police station was completely destroyed by the explosion of a lorry driven by a suicide bomber, which broke through a police barrier and blew up against the station."
A security official said the two attacks on police centres in the western neighbourhood of Golan and the eastern area of Shurta took place "almost at the same time at around 0800 GMT."
Fallujah, 50 kilometres (30 miles) from Baghdad, is one of the main cities in the western province of Anbar, which was the epicentre of the Sunni-led rebellion against US forces in the months following the March 2003 invasion.
The city was virtually razed in 2004 in one of the biggest assaults launched by US forces.
In September, the United States handed control of Anbar to Iraqi forces.
