More Chlorine Attacks in Iraq

They did it again ... three times.

Three suicide bombers driving trucks rigged with tanks of toxic chlorine gas struck targets in heavily Sunni Anbar province including the office of a Sunni tribal leader opposed to al-Qaida. The attacks killed at least two people and sickened 350 Iraqi civilians and six U.S. troops, the U.S. military said Saturday.

The violence started about 4:11 p.m. Friday when a driver detonated explosives in a pickup truck carrying chlorine at a checkpoint northeast of the provincial capital of Ramadi, wounding one U.S. service member and one Iraqi civilian, the military said in a statement.

Two hours later a dump truck exploded in Amiriyah, south of Fallujah, killing two policemen and leaving as many as 100 residents with symptoms of chlorine exposure ranging from minor skin and lung irritations to vomiting, the military said.

Another suicide bomber detonated a dump truck containing a 200-gallon chlorine tank rigged with explosives at 7:13 p.m. three miles south of Fallujah in the Albu Issa tribal region, the military said. U.S. forces found about 250 local civilians, including seven children, suffering from symptoms related to chlorine exposure, according to the statement. Police said the bomb was targeting the reception center of a tribal sheik who has denounced al-Qaida.

Four other bombings have released chlorine gas since Jan. 28 ... The primary effect of the chlorine attacks has been to spread panic. Although chlorine gas can be fatal, the heat from the explosions can render the gas nontoxic. Victims in the recent chlorine blasts died from the explosions, and not the effects of the gas.

They haven't gotten big casualty counts out of these things - and when you use pickup trucks and dump trucks as your delivery vehicles, you're probably not going to get much. But the fact that they continue to use chlorine as a weapon may indicate a willingness to go through the learning curve.

It's worth noting that these three attacks took place in Anbar province, where al Qaeda has a well-documented presence. Also, two of the targets were al Qaeda opponents.

This is worth watching. (Also see this post.)
