The US military carried out airstrikes on three facilities used by the Iraq-based Kataib Hezbollah and “affiliated groups” on Monday night after an attack injured three US troops, leaving one in critical condition, the White House said.

A US Central Command statement said early assessments indicated that the US airstrikes, ordered by President Joe Biden, “likely killed a number of Kataib Hezbollah militants.”

The Iranian-backed militant group earlier claimed credit for using a one-way attack drone to target the US forces on Erbil Air Base on Monday morning, the White House said.

A statement from US National Security Council spokesperson Adrienne Watson said the US airstrikes on “three locations utilized by Kataib Hezbollah and affiliated groups focused specifically on unmanned aerial drone activities.”
