The contents of the publication are dated Sept. 15, and an editor’s note in the magazine urges lone Islamic extremists, or those not formally affiliated with a specific terrorist group, to take up arms against America and carry out a so-called “lone wolf” attack.

“Editor Yahya Ibrahim, after praising the January 2015 Charlie Hebdo attack [in France], notes that ‘in the coming days we are waiting for the anniversary of … the blessed 9/11 operation,’ and states that ‘We at Inspire, and in the cause of the events of 9/11, encourage the Muslims in the West to join the Lone Jihad caravan,’” according to MEMRI’s report on Al Qaeda’s latest call for violence.

The manual lays out “for the Lone Mujahid ways and methods to enable him to give victory to the religion and the prophet.”

Included is a step-by-step guide to carry out a terrorist operation without being detected by U.S. authorities.
