Boko Haram, the Nigeria-based Islamist terror group, has pledged allegiance to ISIS, according to an audio message purported to be from Boko Haram’s leader, Abubakar Shekau.
In the audio, which was posted online Saturday, the speaker says Boko Haram is announcing its “allegiance to the Caliph of the Muslims, Ibrahim ibn Awad ibn Ibrahim al-Husseini al-Qurashi,” which is another name for ISIS leader Abu Bakr al-Baghdadi.
CNN has not been able to independently authenticate the message.
