Dozens of American citizens have fought for the Shabab, and there have been unsubstantiated reports that one of the mall attackers may have been American. http://www.nytimes.com/2013/10/11/world/africa/norway-kenya-mall-siege.html?ref=world&_r=0
Many questions about the Kenyan mall siege remain unanswered nearly three weeks after it ended. Investigators have not yet made clear how many assailants were involved or what countries they came from. Kenyan officials have said publicly that as few as 4 or as many as 15 militants may have been involved.
The television channel TV2 in Norway reported this week that Abdikadir Mohamed Abdikadir, the senior Shabab leader known as Ikrimah, lived in Norway for several years. The channel said he moved to Norway in 2004 and applied for asylum. He then traveled between Somalia and Norway several times, it said, and left Norway for good in 2008 before his asylum application was completed.
The Norwegian newspaper Verdens Gang reported on Thursday that the person the Norwegian authorities are investigating as a possible mall assailant is not Mr. Abdikadir. The newspaper did not name the suspect. NRK, the state broadcaster, said the man was in his 20s and grew up and went to school in Norway.
