Born in December 1977, Yasein Taher was a member of a cell of al Qaeda terrorists based in Lackawanna, New York (near Buffalo). The cell is commonly known as the Buffalo Six or Lackawanna Six. All of its members were recruited by Kamal Derwish and hailed from a community of approximately 3,000 Yemeni Muslim residents of Lackawanna.
In 2001 Taher traveled to Afghanistan where he visited the Al-Farooq al Qaeda training camp near Kandahar and was schooled in the use of weapons; he was present on one occasion when Osama bin Laden visited the camp and addressed its trainees.
The other members of the Lackawanna Six were Mukhtar Al-Bakri, Sahim A. Alwan, Faysal Galab, Yahya A. Goba, and Shafal Mosed. A suspected seventh cell member, Jaber Elbaneh (a U.S. citizen born in September 1966) remains at large and is believed to be hiding in Yemen.
In May 2003 Taher pleaded guilty to "providing support or resources to a foreign terrorist organization" and was sentenced to eight years in prison.
