Al Qaeda calls for car bombs in US cities, other 'crusader' countries

The spring 2014 edition of Inspire magazine, seen above, urges jihadists to target specific U.S. locations using car bombs. Detailed instructions and simple diagrams on every step are provided.

Al Qaeda is calling on terrorist affiliates to detonate car bombs in major U.S. cities, including New York, Washington, D.C., and Los Angeles, in the latest edition of its Inspire magazine.

The issue comes nearly a year after the Boston Marathon bombing, and as the city readies new security measures for this year's race, being held next month. Inspire is the same magazine that included instructions for how to make pressure cooker bombs, which were used in last year's Boston attack.

The magazine’s Spring 2014 issue urges jihadists to target heavily populated events such as political rallies and sporting events, both in the United States and abroad -- including in Great Britain, France and other “crusading” countries.

“Choosing the place and time is a crucial factor to success in any operation,” the magazine reads. “Choose targets in your own country. You know the enemy better, you are within … The important thing is that you target people and not buildings.”

Would-be bombers also are urged to consider launching attacks during “election seasons” and between Christmas and New Year’s Eve. Specific targets are also cited, including Chicago’s "Sears Tower" (now called the Willis Tower), military bases in northern Virginia and soccer stadiums in Great Britain, particularly during Premier League matches.

“Disguise yourself during the operation, appear fat (add some clothes on you), change your complexion, be a 'clone', use any mask (believe me embarrassment is the last thing you will think about), wear a mask suitable for the festival, white beards on 25th Dec,” it reads. “All in all, be creative brother. The most important part to hide is your eyes and around.”

The issue also contains extremely detailed, “absolutely simple” instructions on how to build such a bomb.

“My Muslim brother, before you start reading the instructions, remember that this type of operation, if prepared well and an appropriate target is chosen, and Allah decrees success for you, history will never forget it,” the magazine reads. “It will be recorded as a crushing defeat on the enemies of Islam.”
