Iraqi Prime Minister Haider al-Abadi announced the start of an assault to recapture Mosul, the most important Iraqi city held by ISIS, on October 16.
The assault is spearheaded by the Iraqi army and the peshmerga, the armed forces of the Kurdistan Regional Government in northern Iraq. It also includes the Popular Mobilisation Units (PMU), an umbrella group of militia groups loyal to the Iraqi government and based in Iraq’s Shi’a Arab communities, and some other Iraqi militias.
