Islamic State’s lone-wolf tactics inspire al Qaeda’s most dangerous threat to West

Al Qaeda’s most dangerous branch office is focusing more on the single-jihadi terrorist business, muscling in on operations advocated by its Sunni extremist competitor, the Islamic State group.

Al Qaeda in the Arabian Peninsula (AQAP), with headquarters in Yemen, recently sent out tactical guidance for followers on how to copy the carnage inflicted by the lone attacker who drove a truck into a crowd and then stabbed a security guard in the shadow of the British Parliament in London.

The Yemeni branch is widely seen as al Qaeda’s most dangerous franchise because of its focus on attacking the U.S. homeland. It strives to build bombs that can be secreted onto airliners.
