A truck bomb that combined explosives with chlorine gas blew up in southern Baghdad on Wednesday, and officials said it might represent a new and deadly tactic by insurgents against Iraqi civilians.I predicted this type of attack here, so I get a chance to use this:
It was at least the third truck bomb in a month to employ chlorine, a greenish gas also used in World War I, which burns the skin and can be fatal after only a few concentrated breaths. The bomb killed at least two people and wounded 32 others, many of them sent to hospitals coughing and wheezing, police and medical officials said.
Insurgents have shifted tactics to focus on helicopters, and on Wednesday one group forced down an American Black Hawk helicopter, the eighth such incident since Jan. 20. Roadside bombs have been adapted to punch through heavily armored Humvees. Attacks on Americans also now include coordinated assaults from multiple locations, with a mix of weapons and in at least one case, counterfeit American uniforms and vehicles.
