(KUNA) -- A bomb struck a Sunni mosque northeast of Baghdad on Friday, killing 10 people and wounding 25 others in the same town where al-Qaeda leader in Iraq Abu-Musab Al-Zarqawi was killed earlier this month, a security source said. The source told KUNA the explosion occurred in front of "Habhab" mosque in the security-unstable Diyala province. He added the explosion severely damaged the mosque and the cars and nearby buildings. Meanwhile, an Iraqi woman was freed by the Iraqi police after security forces stormed her detention place in the northern city of Kirkuk. An Iraqi police source told KUNA that the housewife hostage was hand-tied when found in a car with a suspicious person. The source added that the suspect informed interrogators about four other people, suspected of conducting terrorist acts. In a related story, unidentified gunmen shot dead two traffic police officers in downtown Kirkuk.
