Abu Mahdi al-Muhandis

Jamal Ja'far Muhammad Ali Al Ibrahim (Arabic: جمال جعفر محمد علي آل إبراهيم Jamāl Jaʿfar Muḥammad ʿAlīy ʾĀl ʾIbrāhīm, 16 November 1954 – 3 January 2020), better known by his kunya Abu Mahdi al-Muhandis (Arabic: أبو مهدي المهندس, lit. 'Father of Mahdi, the Engineer'), was an Iraqi paramilitary leader and former chief of staff of the Popular Mobilization Forces (PMF). At the time of his death, he was deputy chairman of the PMC.

From 1977, he was an opponent of Saddam Hussein. He became the commander of volunteer militias that grew from the need to combat ISIS, including the Kata'ib Hezbollah paramilitary group, which is designated a terrorist group by the governments of Japan, the United States and the United Arab Emirates; and prior to that worked with the Iranian Revolutionary Guards (IRGC) against Saddam's regime. Muhandis was on the United States list of designated terrorists since 2009.
