BAGHDAD (AFP) - Bombers and gunmen killed at least seven people in attacks in central and southern Iraq on Monday, the interior ministry and security officials said. Three people, two of them soldiers, died when gunmen opened fire at an army checkpoint in Ghazaliyah, a mainly Sunni suburb of western Baghdad, a ministry official said. Eight other people were wounded. A roadside bomb blast targeting a police patrol near the agriculture ministry in the centre of the city killed two civilians and wounded six people, the official added. On Sinaa Avenue in downtown Baghdad, a similar device also aimed at a police patrol wounded seven people, three of them policemen. In Iskandiriyah, a town to the south of the Iraqi capital, a man was killed and his son wounded in a bombing also targeting police. Gunmen in the northern city of Mosul, Iraq's second largest and a hotbed of insurgents, shot dead a policeman in plainclothes on the street, a security official. And a member of the secular Iraqi National List of former premier Iyad Allawi, Amer Shaaban al-Haibi, was seriously wounded in a bomb attack and risks having a foot amputated, security and medical sources said. Meanwhile, a military operation in the northern Iraqi province of Nineveh, where Al-Qaeda insurgents still have a foothold, has netted about 100 suspects, a defence ministry spokesman said on Monday. General Mohammad al-Askari told AFP that three divisions, two from the army and the other police, making up a combined 15,000-strong force had been deployed for the operation launched on Friday, codenamed New Hope. The operation has been taking place in the northwest of the province, near the border with Syria, according to local residents. "The plan was decided before the January provincial elections to ensure stability in the province," said Askari. "Niniveh and Diyala (northeast of Baghdad) need repeated military operations to put pressure on the terrorists."
