Six people were killed in attacks in central and northern Iraq on Monday, including five who died in a spate of bombings in the former insurgent bastion of Fallujah, officials said.
In Fallujah, just west of Baghdad, three bomb attacks in close succession killed five people and wounded 18 others.
An initial car bomb detonated in the center of the city, killing five people and wounding eight, Anbar provincial police spokesman First Lieutenant Ali al-Amiri and doctor Omar Dalli from Fallujah hospital said.
Two more attacks -- a motorcycle bomb and a roadside bomb -- in the east and west of the city respectively wounded 10 more people, including two traffic policemen, the officials said.
Explosives experts defused one more car bomb and two roadside bombs.
Fallujah is in western Sunni Arab Anbar province. It was one of several towns along the Euphrates valley that became Al-Qaeda strongholds after the 2003 U.S.-led invasion that ousted Saddam Hussein.
However, from 2006, local Sunni tribes sided with the U.S. military and unrest dwindled in Anbar as rebel fighters were ejected from the region.
Another attack on Monday in the disputed northern city of Kirkuk left intelligence service First Lieutenant Abbas Fatih Ahmed dead when a magnetic “sticky bomb” attached to his car detonated shortly after he left his house, deputy provincial police chief Major General Torhan Abdulrahman said.
Violence across Iraq is down from its peaks in 2006 and 2007, but attacks remain common. A total of 126 Iraqis were killed in April, according to official figures.
