A Somali-American teenager arrested Friday on suspicion of plotting to bomb a holiday ceremony in Portland, Oregon, told an undercover FBI employee that he wrote articles published in an English-language jihadist magazine, including a story on fitness, an FBI affidavit says.
Mohamed Osman Mohamud, 19, told the undercover operative last summer that he had written articles for the online magazine Jihad Recollections under a pen name, according to an FBI affidavit filed with Mohamud's arrest warrant.
One of the articles Mohamud claimed to have written was "Getting in shape without weights," which was published in the inaugural issue of Jihad Recollections in April 2009, according to the affidavit.
In the article, the author - identified as Ibn al-Mubarak - writes that jihadists must prepare their bodies for war and "train as hard as possible in order to damage the enemies of Allah as much as possible."
The article implores readers to train without weights, in part because¬†using them is "unrealistic for the Mujahid in the front lines anywhere in the world today," and because gyms are not Islamic environments, with their "music, semi-naked women [and] free mixing."
The piece describes stretches and warm-ups before instructing on ways to sculpt one‚Äôs legs (suggestions include walking at least 90 minutes a day, doing interval runs, crawling long distances and sitting against a wall for long periods) and strengthen one‚Äôs arms (100 to 150 push-ups per day, pull-ups, walking on hands).
"We find that [weights are]¬†... a major setback for the Americans and the NATO Crusading army as they cannot go to any battlefront without carrying along with them their bench, squat sets and sometimes even their machines," the article says.
U.S. authorities say Mohamud was arrested in connection with a plan to detonate what he believed to be a vehicle bomb at Portland's Christmas tree lighting on Friday night. He attempted to detonate the device, which was a fake planted by authorities in an undercover operation designed to undermine him, the Justice Department said.
A resident of Corvallis, Oregon, and a student at Oregon State University, Mohamud was arrested on suspicion of attempting to use a weapon of mass destruction, the FBI said. He will make his initial appearance Monday in federal court in Portland, the Justice Department said.
The arrest was the culmination of a long-term undercover operation during which Mohamud, a naturalized U.S. citizen from Somalia, was monitored closely as the alleged plot developed, the Justice Department said. Mohamud made the article claim to an operative involved in that undercover operation, according to the affidavit.
Mohamud¬†said he wrote two other articles for Jihad Recollections, and that he also sent an article to another jihadist publication, Inspire, according to the affidavit. The court document does not identify those articles.
U.S. counterterrorism officials have said Jihad Recollections was produced by former North Carolina resident Samir Khan, who those officials now say they believe is living in Yemen. Intelligence officials also¬†suspect Khan is the driving force behind Inspire.
