Kata'ib Hezbollah or the
Hezbollah Brigades, is a radical Iraqi Shiite paramilitary group which is a part of the Iraqi Popular Mobilization Forces (PMF), staffing the 45th, 46th, and 47th Brigades. During the Iraq War (2003–11), the group fought against Coalition 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 in a US drone attack in 2020. Thereafter, Abdul Aziz al-Muhammadawi became the new leader of the PMF. The group seeks to establish an Iran-aligned government in Iraq, expel American forces from the country, and advance the regional and international interests of Iran in Iraq and the region. The group is responsible for killing hundreds of U.S. soldiers and takes a central part in carrying out attacks against U.S. targets in Iraq and acts as part of the Axis of Resistance. Kata'ib Hezbollah has received extensive training, funding, logistic support, weapons, and intelligence from the Quds Force of Iran's Islamic Revolutionary Guard Corps (IRGC).
