About 20 fighters of the Iraqi Kataib Hezbollah militia forces have been injured in a US airstrike on their headquarters in the city of Hillah in the central part of the Iraqi region of Babylon, news agency Shafaq News reported on Tuesday.

"A camp of Harakat al-Nujaba, one of Shiite groups, was bombed from the air, after which the Pentagon reported strikes on three Kataib Hezbollah facilities in Iraq.

According to initial reports, about 20 fighters were injured," the Iraqi news agency quoted an anonymous source as saying.

The strikes have been presumably carried out from a drone, the source said, adding that three explosions were heard and followed by heavy artillery fire, as cited by the news agency.

Earlier in the day, the Pentagon said that the US had carried out strikes against three targets of Kataib Hezbollah and associated groups in Iraq in response to a drone attack on Erbil Air Base in northern Iraq, which left three US service members wounded.

The US Central Command said on X that the airstrikes reached their targets and destroyed facilities used by "Iranian sponsored Kataib Hezbollah terrorists and affiliated groups."
