Iraq’s security forces have again been the target of attack by rebels fighting US-led forces and the country’s interim government.Up to five members of the National Guard were reported to have been killed and 13 others wounded when their base north of the Baghdad was hit by mortar rounds. Four shells fell on offices in the early morning attack in Mushahidah. Coalition forces helped evacuate the wounded by helicopter to military medical facilities for treatment. Insurgents regularly strike at Iraqi police and soldiers who are seen as collaborating with the US and its allies. The guerrillas also frequently aim at Iraq’s infrastructure – a pipeline near Kirkuk was the latest target in an attempt to sabotage the oil industry. Firegighters battled for hours to bring the flames under control after the pipeline was blown up. Oil is vital to the interim government’s efforts to restore economic stability to the country.
