The Islamic State on Thursday announced that it has a new leader, but provided little information on the true identity or background of the man who will now oversee the global terrorist organization.

The new leader, Abu al-Hasan al-Hashimi al-Qurashi, was unveiled in an audio message released on Islamic State social media accounts that also confirmed the death of the group’s previous leader, who American officials say blew himself up during a U.S. commando raid on his hide-out in northwestern Syria last month.

Mr. al-Qurashi takes the reins of a terrorist group that is a shadow of its former self in terms of members and power, but still causes havoc in poorly governed areas in Syria, Iraq, parts of Africa and elsewhere.
