Al-Qaida is using the latest edition of its magazine to call for car bombs across the United States and other "crusader countries."
The Spring 2014 edition of Inspire details how to build a bomb and suggests the best way to plan and execute a successful attack.
Unsurprisingly, the magazine notes that "America is our first target," and it recommends Washington (specifically restaurants and bars on M Street), Northern Virginia (including Arlington and Alexandria), Chicago, New York, and Los Angeles as specific targets.
In addition, it notes that a potential terrorist should look for places "flooded with individuals," including sports events—specifically the U.S. Open tennis tournament, campaign events, festivals, and holiday gatherings on Christmas, New Year's Eve, or New Year's Day.
"The important thing is that you target people and not buildings," notes the article, located in the magazine's "Open Source Jihad" section.
And with the Boston Marathon coming up next month, the article strikes a soberingly familiar note with a recipe on how to build a bomb using a pressure cooker—the type used in the April 2013 attack.
Top defense and Homeland Security officials have warned about an increasing risk from individuals who work alone to plan or carry out a terrorist attack without direct instructions from a terrorist organization.
DHS Secretary Jeh Johnson said last month that the Boston Marathon bombing could be "a sign of the future" and that terrorist threats from so-called "lone wolf" or "self-radicalized" terrorists are in many ways harder to detect.
DHS didn't immediately respond to a request for comment on the magazine article.
