A letter recovered in Osama bin Laden’s compound reveals that a senior AQIM commander recommended that his group train Boko Haram’s forces. Other official sources confirm that AQIM did provide the training and also groomed part of Boko Haram’s leadership. However, one of the Boko Haram leaders identified in the letter later cofounded a splinter group known as Ansaru, which rejects Boko Haram’s policies. Ansaru has been supported by AQIM.
Boko Haram’s leader, Abu Bakr Shekau, has pledged allegiance to the emir of the Islamic State, Abu Bakr al Baghdadi.
Divisions between Boko Haram and rival Ansaru have become more pronounced over the past several weeks.

Boko Haram has adopted al Qaeda’s tactics and has communicated with top al Qaeda leaders to coordinate in the global jihad. Ansaru, a Boko Haram splinter group, was also added to the terrorism list.
