In its upcoming issue, the al Qaeda-backed magazine Inspire praises the alleged Boston Marathon bombers as heroes and encourages readers in the United States to follow their example.
According to an English copy of the magazine obtained by Flashpoint Partners, an American group tracking jihadist websites, the issue also has a section heralding the killing of a British soldier in London last week.
The authors of the magazine, published by al Qaeda in the Arabian Peninsula based in Yemen, argue April's deadly violence in Boston proves that lone-wolf attacks can be effective in the United States. The issue also warns Americans that they're not safe against such "unstoppable" operations.
Investigators believe that alleged Boston bomber Tamerlan Tsarnaev, who was killed days after the attack, accessed Inspire magazine, which had instructions on bomb-making, a law enforcement official told CNN this month.
According to analysts, the explosive devices used in the attack that killed three and injured more than 260 others had striking similarities to a bomb recipe in the first issue of the magazine in June 2010.
"How to build a bomb in your Mom's kitchen" has been downloaded by militants in multiple Islamist terrorist plots.
The upcoming issue, which falls just under 40 pages, calls on American Muslims to follow those who masterminded the Boston attacks. And as long as simple materials-like the pressure cooker allegedly used in the Boston bombing - remain legal, such acts can be carried out with ease, the magazine says.
"Lone-Jihad is impossible to counter and stop, except when basic cooking ingredients and building material become illegal," the magazine states. Embedded among the articles are glossy photos of the carnage from the bombing near the Boston Marathon finish line.
One section, "An eye for an eye," features a graphic of a bloody knife and an image of a meat cleaver wielding-suspect in the deadly daylight attack on a British soldier in Woolwich.
The author says "the message of these young men has been conveyed to the whole world, including every Britain, every westerner, every kafar (non-believer) whose hands have Muslim blood."
In a separate letter, "Jones the Rebel" instructs American Muslims to "break down these psychological barriers which hinder us from attacking this enemy ... beware of belittling yourself and your capability."
The Boston bombings, the author states, "revealed the power of the lone jihad operation" and encourages readers to "take things into your hands."
It should be noted that the quality of English in the new issue is significantly lower than in previous editions.
"The Boston events, the road accidents, the poisoned letters, disregard of the people behind them, indicate that the control of your security has broken away and operations against you has taken a path which can be controlled not," Qassim ar-Reimy, a senior commander for al Qaeda in the Arabian Peninsula, writes in a message to Americans.
Making the bombs, he argues, is a skill now within every individual's reach. Another article features a graphic of Tamerlan Tsarnaev depicted in paradise.
While no physical links have been found between Tsarnaev and his brother, Dzhokar, and al Qaeda, Inspire magazine is nonetheless taking credit for being a catalyst for the attacks, says CNN Terrorism Analyst Paul Cruickshank.
"They're opportunistically taking credit for this, saying, 'We encouraged these guys. We gave them instructions and look what happened.' And they're trying to encourage others to do the same," Cruickshank told CNN, adding the magazine is "very difficult" to shut down because of its ability to disseminate online.
