Authorities said attacks in Iraq have killed at least four people as government troops continue to battle Al-Qaeda-linked militants in the Western Anbar province. A suicide bomber crashed his explosives-laden truck into a police station in the Northern city of Kirkuk, killing two people and wounding 55, according to Maj. Raid Emad Rasheed, AP quoted. In a separate incident, a roadside bomb hit an army patrol on the outskirts of Baghdad, killing one soldier and wounding another, police said. Another bomb struck a patrol of Sunni militiamen in a different part of Baghdad, killing one and wounding four. A medical official confirmed the figures. The comments were given anonymously.
