BAGHDAD — Three suicide bombers driving trucks rigged with tanks of toxic chlorine gas struck targets in heavily Sunni Anbar province Friday, including the office of a Sunni tribal leader opposed to Al Qaeda.
The attacks killed at least two people and sickened 350 Iraqi civilians and six U.S. troops, the U.S. military said Saturday.
There is a mounting power struggle between insurgents and the growing number of Sunnis who oppose them in Anbar, the center of the Sunni insurgency, which stretches from Baghdad to the borders with Syria, Saudi Arabia and Jordan.
The Anbar assaults came three days after Prime Minister Nouri al-Maliki, a Shiite, traveled there to reach out to Sunni clan chiefs in a bid to undermine tribal support for the insurgency.
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.
Iraqi authorities said at least six people were killed and dozens wounded when the truck blew up in a line of cars waiting at a checkpoint. The U.S. did not confirm the Iraqi report.
Ahmed Kuhdier, a 32-year-old taxi driver, said the blast sent up a plume of white smoke that turned black and blue.
“Minutes later, we started to smell nasty smells. I saw people coming form the explosion site and they were coughing and having trouble breathing,” he 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 Qaeda.
Four other bombings have released chlorine gas since Jan. 28, when a homicide bomber driving a dump truck filled with explosives and a chlorine tank struck a quick-reaction force and Iraqi police in Ramadi, killing 16 people.
The U.S. military has warned that insurgents are adopting new tactics in a campaign to spread panic.
The most recent such attack occurred Feb. 21 in Baghdad, killing five people and sending more than 55 to hospitals, a day after a bomb planted on a chlorine tanker left more than 150 villagers stricken near Taji, 12 miles north of the capital.
A previously unannounced homicide car bombing in Ramadi involving chlorine killed two Iraqi security officers and wounded 16 other people, including 13 civilians, on Feb. 19, the military said Saturday.
The military said last month that U.S. troops found a car bomb factory near Fallujah with about 65 propane tanks and ordinary chemicals it believed the insurgents were going to try to mix with explosives.
Maj. Gen. William Caldwell, the chief U.S. military spokesman, called it a “crude attempt to raise the terror level.”
Chlorine, which irritates the respiratory system, eyes and skin at low exposure and can cause death in heavier concentrations, is easily accessible. It is used for water purification plants, bleaches and disinfectants.
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, not the effects of the gas.
Friday’s strikes underscore the increasingly violent struggle for control of Anbar, a center for anti-U.S. guerrillas since the uprising in Fallujah in 2004 that galvanized the insurgency.
In the past year, some major Sunni tribes have broken with the Al Qaeda-linked insurgents, a move that has led to a new sense of optimism among U.S. officials in Anbar.
Al-Maliki on Tuesday made his first trip to Anbar province, meeting with influential clan chiefs whom the U.S. and the Iraqi government are cultivating. He expressed optimism the violence could be stopped and promised the area would not be forgotten as U.S. and Iraqi forces focus on a security sweep to stop the sectarian violence in Baghdad.
Bombings and shootings targeted police patrols elsewhere in Iraq Saturday, killing five policemen, including two who died after a homicide car bomber struck the checkpoint they were manning near a Sunni mosque in western Baghdad.
At least 34 other Iraqis were killed or found dead in attacks throughout the country, including five civilians shot to death in separate attacks in Diyala province northeast of the capital.
Officials also said the director of the Sunni Endowment for mosques in Diyala, Fouad Mahmoud Attaya, was abducted earlier this week by gunmen in Baqouba and an investigation was under way.
A U.S. soldier was shot to death in fighting in the provincial capital of Baqouba, the military said, raising to 85 the number of American troops who have died since the Baghdad security plan was launched on Feb. 14. Twenty-three of those were in Anbar.
Gunmen abducted a radio newscaster and his driver in a predominantly Sunni neighborhood in western Baghdad, the station’s director said.
Karim Manhal, a newscaster with Radio Dijla, and his driver were seized by four masked men in the Jami’a neighborhood near the station’s headquarters, director Karim Yousif said. A female staffer who was with them in the car was released, he said.
Radio Dijla, named after the Arabic name for the Tigris River, was created in 2004 as Iraq’s first independent talk radio station.
