A terror magazine encouraged its readers to set off car bombs, suggesting Times Square a viable target and causing severe concern for the NYPD.
The magazine, titled Inspire, also told readers how to build bombs that are more deadly than the ones used during the Boston Marathon in April 2013, police told the New York Daily News.
"We are certainly very concerned by Inspire," Police Commissioner Bill Bratton told the newspaper. "Among the photos and the encouragement of where to attack there is a photo of Times Square, 47th and Broadway."
The magazine offered details on how to kill the most amount of people.
"As for the field target for the car bomb, you have places flooded with individuals, e.g. sports events in which tens of thousands attend, election campaigns, festivals and other gathering (sic)," the Times of Israel reported according to the Daily News.
The magazine, in its 12th edition, is published by al-Qaeda in the Arabian Peninsula. The brothers suspected in the Boston race bombings, Tamerlan and Dzhokhar Tsarnaev, are believed to have used the magazine to learn how to assemble the pressure cooker-made explosives they allegedly used.
Three people lost their lives and 264 people were injured when the bombs detonated. Tamerlan was killed during a shootout with police and Dzhokhar is expected to face trial.
"Inspire, if we understand it correctly, was the inspiration, if you will, for the Boston Marathon bombers," Bratton told the Daily News. "The instructions on how to build the devices that they in fact were able to build."
Another bomb-plot suspect, Faisal Shahzad, was arrested after a car bomb he allegedly planted in Times Square in May 2010 failed to detonate. The magazine has instructions on how to build a similar car bomb, according to the Times of Israel.
The NYPD will intensify its terrorism watch for the time being.
"It is a magazine that is very widely read by that world and it is an area that we are going to stay very focused on," Bratton told the Daily News.
