Al-Qaeda this week published an online magazine featuring instructions on how to build homemade car bombs and an appeal to Muslims to attack UK and US targets in the vein of the Boston bombers.

The English-language magazine, entitled ‘Palestine: Betrayal of the Guilty Conscience Al-Malahem’, urges Muslims in the West to assemble pressure cooker bombs like those used to attack the Boston marathon last year.

In a list of “examples of targets,” the magazine suggests attacks on the UK’s Royal Military Academy at Sandhurst, MI5’s Thames House and Marks & Spencer department stores during Friday prayers, so as to avoid harming Muslims.

The list features US targets including Times Square, casinos in Las Vegas, Georgia Military College, the US Air Force Academy in Colorado Springs and the General Atomics headquarters in San Diego. It also suggests attacks on Israeli, British and American company headquarters and holiday destinations abroad, oil tankers and busy train stations.

A nine-page spread offers instructions on how to “make a bomb in the kitchen of your Mom,” step-by-step photographs, a shopping list, and admiring words about Boston bombers the Tsarnaev brothers.

“This recipe gives you the ability to make a car bomb even in countries with tight security and surveillance,” one article reads, before providing a list of supplies including cooking gas, oxygen gas, a barometer, decoration lamps and matches.

“My Muslim brother: we are conveying to you our military training right into your kitchen to relieve you of the difficulty of traveling to us,” it reads.

“If you are sincere in your intentions to serve the religion of Allāh, then all what you have to do is enter your kitchen and make an explosive device that would damage the enemy if you put your trust in Allāh and then use this explosive device properly.”

A timeline of terror attacks, including 9/11 and the Boston bombings is concluded with a blank entry marked '201?' implying a terror attack on American or British soil is planned for the near future.

“The timeline concludes with the date 201?’ and blank spaces and question marks for the photo and information of the next attack - implying that it is coming soon,” Steve Stalinsky, of the Middle East Media Research Institute, told Fox News.

“Both AQAP [Al-Qaeda in the Arab Peninsular] and IS [Islamic State], as well as every other al-Qaeda branch and offshoot, is relying on US social media companies including Twitter and YouTube for their cyber-Jihad efforts,” Stalinsky said.

“There could be some envy by AQAP that IS is now getting all the headlines.”

The magazine is a supplement to the terror group’s Inspire magazine, aimed at encouraging Muslims in the West to carry out lone-wolf terror attacks. “Inspire Magazine's goal is to empower Muslims. And what is empowerment without being strong, powerful and intelligent?” the publications reads.

“In this section, we give you strength, power and intelligence. Believe me, using car bombs gives you all that.”
