In a surprise move, the most powerful Iran-backed militia in Iraq, Kataib Hezbollah, announced on Tuesday the suspension of its military operations against US forces in the region two days after a drone attack killed three US service members and wounded dozens of others.

“We are announcing the suspension of military and security operations against the occupation forces (US troops) – in order to prevent embarrassment to the Iraqi government,” Kataib Hezbollah said in a statement.

“We will continue to defend our people in Gaza in other ways, and we recommend to the brave Mujahideen of the Free Hezbollah Brigades to [carry out] passive defense (temporarily) if any hostile American action occurs towards them.”

The group is considered the most powerful armed faction in the Islamic Resistance in Iraq, an umbrella group of Iran-backed militias in the country. The US holds Iran broadly responsible for arming and supporting these groups and has specifically singled out Kataib Hezbollah as likely to have carried out the deadly attack on Sunday.
