The US carried out airstrikes against a pro-Iran militant group in Iraq Sunday, killing 19 fighters, two days after a rocket attack that killed an American civilian contractor.
A few hours after the strikes, four rockets exploded near a base housing US troops close to Iraq’s capital without wounding anyone, an Iraqi security official told AFP.
The US strikes, which also hit Syria, came after a barrage of 30 or more rockets was fired on Friday at the K1 Iraqi military base in Kirkuk, an oil-rich region north of Baghdad, killing a US civilian contractor and wounding four US service members as well as Iraqi security forces.
The fighters were killed by the US strikes in western Iraq, while several were wounded, according to an official from the Tehran-backed Hashed al-Shaabi paramilitary force.
“In response to repeated Kata’ib Hizbollah [KH] attacks on Iraqi bases that host… coalition forces, US forces have conducted precision defensive strikes against five KH facilities in Iraq and Syria,” a Pentagon spokesman said in a statement.
The strikes against three locations in Iraq and two in Syria “will degrade KH’s ability to conduct future attacks” against coalition forces, the statement added.
“KH has a strong linkage with Iran’s Quds Force and has repeatedly received lethal aid and other support from Iran that it has used to attack” coalition forces, the Pentagon said, referring to the external arm of Iran’s Revolutionary Guards.
The military spokesman for Iraq’s outgoing Prime Minister Abel Abdel Mahdi decried “a violation of Iraqi sovereignty.”
Another powerful pro-Iran faction, Assaib Ahl al-Haq – whose leaders were recently hit with US sanctions – called for Americans to withdraw from Iraq.
“The American military presence has become a burden for the Iraqi state and a source of threat against our forces,” it said in a statement.
“It is therefore imperative for all of us to do everything to expel them by all legitimate means.”
‘Caught in the middle’
US-Iran tensions have soared since Washington pulled out of a landmark nuclear agreement with Tehran last year and imposed crippling sanctions.
Baghdad – which is close to both countries – risks being caught in the middle.
In Iraq’s neighbor Syria, Shiite powerhouse Iran backs the government of President Bashar al-Assad in an eight-year civil war.
Friday’s attack on the K1 base in Kirkuk involved a direct hit on an ammunition depot caused secondary explosions, and four more rockets were found in their tubes in a truck at the launch point, according to a US official who spoke on condition of anonymity.
Federal security forces, Shiite militia units and ISIS sleeper cells all have a presence in Kirkuk province, which is claimed by both Iraq’s autonomous Kurdistan Region and federal authorities.
Friday’s attack and the US retaliation come as Iraq is gripped by its biggest anti-government street protests since the US-led invasion of 2003 that toppled dictator Saddam Hussein.
Protesters, many of whom grew up in the post-Saddam era, have vented their anger at a government they consider inept, corrupt and beholden to Iran.
Protest related violence has claimed about 460 lives, most of them demonstrators, and left some 25,000 people wounded, but rallies and sit-ins have continued.
Since October 28, at least 11 attacks have targeted Iraqi military bases where US soldiers or diplomats are deployed, including five rockets that hit Al-Asad airbase on December 3, just four days after US Vice President Mike Pence visited troops there.
A US source has said pro-Iran factions in Iraq are now considered a more significant threat to American soldiers than ISIS, whose sweeping offensive in 2014 saw Washington deploy thousands of troops to the country.
