After much questioning whether al-Qaeda (AQ) would pledge to the Afghan Taliban's new leader, Mullah Akhtar Muhammad Mansour, AQ leader Ayman al-Zawahiri swore allegiance to the new chief on August 13, promising to him, "We are your soldiers and your supporters and a brigade of your brigades." This pledge, produced by AQ's as-Sahab Media Foundation and titled, "A Biography of Faithfulness," will serve as test of AQ's leadership strength and the ties to its affiliates.
A week after Chattanooga shooter Mohammad Abdulazeez’s attack, very little is known about his motives, path to radicalization, and network of affiliations. Immediately after the attack, Islamic State (IS) fighters and supporters hailed Abdulazeez as a “soldier of the Islamic State,” but no official messages from IS claiming the attack have yet been made. This silence is noteworthy considering the case of the shooting in Garland, Texas: Not only did IS fighter Junaid Hussain bluntly indicate his connection to this attack, but in less than two days, IS officially announced the shooters to be “two soldiers from the soldiers of the Caliphate.”
Muhammad Youssef Abdulazeez, identified as the July 16, 2015 shooter of four Marines at a Naval Reserve Center in Chattanooga, Tennessee, maintained a blog containing two Islam-focused posts made just three days before the attack.
Ali Shukri Amin, a 17 year-old Islamic State (IS) supporter who plead guilty to conspiring to send support to the group, once maintained a high profile on social media.
Any celebration made after the U.S. raid that killed high-ranking Islamic State (IS) official Abu Sayyaf was likely halted after reports of the group’s take-over of Ramadi.
