A former taxi driver from northern Virginia is now on the list of the world’s most wanted terrorists.

Liban Haji Mohamed, 29, was born in Somalia but became a naturalized citizen of the United States.  The FBI says that Liban is a recruiter for the al-Shabab terrorist network in Somalia.

Liban is the older brother of Gulet Mohamed, who has been fighting the government for four years over his placement on the no-fly list.  The family claims that Liban was harassed by the FBI after advocating for his younger brother and that he’s gone into hiding because he wanted to avoid harassment.

The charges against Liban Mohamed including providing material support to both Al Qaeda and al-Shabab.  The FBI says it’s likely he left the U.S. for Africa in July 2012 but prior to that had been a taxi driver in Fairfax County, Virginia.

“It is important for us to locate Mohamed because he has knowledge of the Washington, D.C., area’s infrastructure such as shopping areas, Metro, airports, and government buildings,” said Carl Ghattas, special agent in charge of the Counterterrorism Division at the FBI’s Washington Field Office. “This makes him an asset to his terrorist associates who might plot attacks on U.S. soil.”

The FBI also said that he was a “close associate” of Zachary Cheeser, a northern Virginia man who was sentenced to 25 years in prison for trying to join al-Shabab in 2011 along with make threats against the creators of the cartoon South Park for a perceived insult to prophet Muhammad.

Liban’s family claims the release from the FBI is nothing more than an attempt to influence the judge in the case Gulet Mohamed has filed.
