Kata'ib Hezbollah

Kata'ib Hezbollah —or the Hezbollah Brigades—is an Iraqi Shia paramilitary group which is part of the Popular Mobilization Forces that are supported by Iran. During the Iraq War (2003–2011), the group fought against coalition occupation forces. It has been active in the War in Iraq (2013–2017) and the Syrian civil war (2011–present). The group was commanded by Abu Mahdi al-Muhandis until he was killed by a US airstrike in Baghdad on 3 January 2020. Thereafter, he was replaced by Abdul Aziz al-Muhammadawi, as the new leader of the Popular Mobilization Unit (PMU).
