At least 10 people were killed Sunday in a series of attacks in western Iraq, said security sources, dpa reported.
The attacks included a botched attempt by insurgents to seize control of a major security building in Ramadi, a main city in the province of Anbar, the sources said.
Security forces killed two suicide bombers and four insurgents in clashes over the control of the building, said a local official. "All insurgents were driven out of the Investigations Directorate building," Mohammed Fathi, the spokesman for the province, told dpa.
The assailants had sought to release colleagues held inside the building, said the official.
Four others, including three policemen, were killed in five bomb blasts that targeted security and government offices in Ramadi, he added.
In the wake of the attacks, local authorities called a curfew in the city, located about 110 kilometres west of the Iraqi capital Baghdad.
But Fathi said that life was back to normal. "The security situation in the province is under full control."
Later on Sunday, security forces carried out massive crackdowns on hideouts of suspected insurgents across Anbar, reported local media. The province has recently seen a surge in violence.
Elsewhere, at least 12 civilians were wounded when a car bomb exploded near police offices north of Baghdad, security sources said.
The bombing in the town of Baiji, 200 kilometres north of Baghdad, also damaged nearby government buildings and stores, the sources said.
The attacks came one day after at least 61 Shiite pilgrims were killed in a suicide bombing in the southern city of Basra.
Fears have grown among Iraqis over an increase in attacks by armed groups after US troops completed their withdrawal from the country in December.
