WASHINGTON — For months, as one young person after another in Minneapolis’s Somali community tried to join the Islamic State terrorist group, rumors circulated of a sinister recruiter who must be luring gullible teenagers and providing the cash to buy air tickets to Syria.
But on Monday, federal officials, announcing their biggest Islamic State recruitment case to date, said there was, in fact, no recruiting mastermind. Instead, for the six men arrested, there was just the camaraderie of sharing an illicit ideology, plus advice and inspiration by phone and Internet from one of their friends, a young Minneapolis man who joined the Islamic State last year.
In other words, said Andrew M. Luger, the US attorney for Minnesota, the circle of friends “recruited each other.” He said they scrounged the money for tickets, selling a car and emptying a college financial aid account, and brainstormed about how to evade the FBI and reach the brutal terrorists they idolized.
The FBI is increasingly concerned about this model of radicalization by peers. Because discussions of the Islamic State took place during pickup basketball games and visits to the mall, the wave of recruitment was difficult for the authorities to detect in advance. It is also a source of distress to parents in the Somali-American community, local activists say, providing no nearby villains to blame for leading their children astray.
The head of the Minnesota FBI office, Richard T. Thornton, said crucial help in stopping the recruits came from inside the Somali community, including a young man who changed his mind about the Islamic State, also called ISIL, and became an informant in January.
“These courageous men and women,” Thornton said of the local Somalis, “decided to do something to prevent more Minnesotans from traveling and dying in support of a terrorist organization which is evil to its core.”
All of those charged were Somali-Americans ages 19-21 from Minneapolis, where four were arrested Sunday. The other two were detained in San Diego, where officials said they had driven to buy fake passports, hoping to cross into Mexico and continue to Syria from there.
A linchpin in the recruitment effort, it turned out, was Abdi Nur, 21, who left Minneapolis in May and successfully reached Syria. Nur, whose story was recounted by The New York Times last month, has become “an active recruiter” who offered encouragement and practical tips to those who wanted to follow his path, Luger said at a news conference.
During a 10-month investigation, the FBI struggled to discover how the Islamic State was luring Minnesotans. Speculation surrounded a local man, Amir Meshal, 31, who had been expelled from two mosques and publicly accused of radicalizing young Muslims. But Meshal, who had vehemently denied supporting the terrorist group, was not charged.
Instead, Luger said, the recruitment was “a peer-to-peer operation” in which friends compared notes on how to raise money for plane tickets and connect with Islamic State travel facilitators in Turkey.
Arrested in Minneapolis were Zacharia Yusuf Abdurahman, 19; Adnan Farah, 19; Hanad Mustafe Musse, 19; and Guled Ali Omar, 20. The two men arrested in San Diego were identified as Abdirahman Yasin Daud, 21, and Mohamed Abdihamid Farah, 21, Adnan Farah’s brother. All were charged with conspiring to provide material support to a designated terrorist organization.
Daud and Mohamed Farah had driven to San Diego in Daud’s car, accompanied by the friend who had become an informant. The informant, who was not named in court documents, had claimed he could get them forged passports to enter Mexico.
In November, in an earlier bid to leave the United States, Abdurahman, Musse, and Mohamed Farah traveled by bus to Kennedy Airport in New York but were prevented from boarding. Their companion, Hamza Ahmed, 19, was removed from a plane minutes after boarding and subsequently charged.
But even after that encounter with the authorities, Luger said, “they never stopped plotting to find a way to get to Syria to join ISIL.” Others in the group were confronted by their parents and blocked from leaving but decided to try again.
The court documents disclose that another Minneapolis man, referred to as “YJ,” evaded the FBI, flew to Turkey in June and called his family from the same telephone number used by Nur after he arrived in Turkey. He appears to have reached the Islamic State.
Those arrested Sunday are among just a few dozen Americans who have traveled or tried to travel to Syria to join the Islamic State.
Those whose plans were discovered by the FBI have been arrested, usually at a US airport as they tried to board a flight.
Those intercepted have been a diverse group, including many women, with ages ranging from the early teens to late 40s, and comprising both converts to Islam and children from Muslim immigrant families.
The largest single group, however, has consisted of Somali-Americans from Minnesota.
