Four days after President Trump announced the ISIS leader, Abu Bakr al-Baghdadi, had blown himself up during a raid by American forces, ISIS confirmed his death and announced his successor, Ibrahim al-Hashemite al-Qurayshi. He is identified as the “emir of the believers” and “caliph” among the Islamic State but is largely unknown outside the ranks of the group.

The Islamic State’s announcement was reported via the Twitter account of the Site Intelligence Group, which monitors online content and propaganda that is shared by ISIS and other extremist militia groups.
