Nine Iraqi soldiers killed in north Baghdad attacks

BAGHDAD - At least nine Iraqi soldiers including a colonel were killed on Tuesday after insurgents fired rockets at an army convoy north of Baghdad and gunmen battled troops at checkpoints in a wave of attacks on security forces.
Iraq's insurgency has ebbed since the height of the war four years ago, but militants tied to al-Qaida and other Sunni Muslim Islamists are hitting Shi'ites and security forces in an attempt to undermine the country's Shi'ite-led government.
Military helicopters opened fire on dozens of gunmen attacking checkpoints along a main route north of Baghdad, police and army officials said.
"Dozens of gunmen attacked army and police checkpoints, and army helicopters opened fire with machine guns at their locations," one police officer, Saif Ali, said by telephone, near the site of the one of the attacks.
