TIKRIT: Gunmen in military uniform broke into the city council and court house in Samarra in northern Iraq on Tuesday, holding the facility for four hours until police and army stormed the compound, the mayor and police officials said.
Four policemen were killed in the fighting, along with three civilians who were visiting the city council and were shot when Iraqi security forces opened fire to retake the site, a senior police officer said.
A further 47 people were wounded, including 30 soldiers and policemen, according to officials at the Samarra hospital. The deputy head of the city council, Ammar Ahmed, and a second member were wounded.
"The Iraqi police and army managed to clear the building," Samarra Mayor Mahmoud Khalaf said. "The situation is under control."
Three fighters, who had holed up in the city council building, detonated their suicide vests rather than surrender, Khalaf said.
The three had stormed the area after a fourth detonated his vest at the entrance of the compound, which is sealed off with blast walls, Police Lieutenant Dhafir Ahmed said.
Two policemen had been racing to help when a parked car bomb blew up their vehicle about 200 meters (yards) from the site. Gunmen had taken the city council's second floor and its roof.
Casualties might have been greater but many staff were attending a meeting across town with the mayor and governor of Salahuddin province, two police officials said.
Samarra has long been troubled by unrest. Sunni militant groups have regularly attacked local Sunni government officials along with the Iraqi army and police.
In late December, gunmen seized the state television channel in Tikrit, the capital of Salahuddin province. The fighters employed similar tactics to those used in Samarra on Tuesday.
Sunni Islamist insurgents have been regaining ground in Iraq over the past year and in recent weeks overran several towns.
Last year was Iraq's bloodiest since sectarian violence began to abate in 2008, with nearly 8,000 civilians killed. More than 700 people died in violence in Iraq in February, the United Nations said last week.
Iraqi Prime Minister Nuri al-Maliki says the upsurge is a spillover from the civil war in neighboring Syria but critics say his own policies are as much to blame for reviving an insurgency that climaxed in 2006-07.
