Maher Farrukh, an al-Qaida analyst for the Critical Threats Project at the American Enterprise Institute said that "AQAP and ISIS cooperate on a tactical level in central Yemen against al Houthi-Saleh forces, they often co-claim attacks and likely share some militants," and that "ISIS' continued presence in Yemen is likely sustained by its cooperation with AQAP, but it does not appear to be growing at this time."
