The Islamic State militant group confirmed the death of its leader Abu Ibrahim Al-Qurashi in a statement Thursday and named Abu Hasan Al-Hashemi Al-Qurashi as his replacement. IS militants have “pledged allegiance” to “Abu Hasan Al-Hashemi Al-Qurashi as an emir over believers and the caliph of Muslims,” the group’s spokesperson said in an audio recording that confirmed the death of the former IS chief along with the group’s ex-spokesman. The former leader blew himself up in early February during a US raid in northwest Syria, an area controlled by rival militants.
