The last and youngest of the "Lackawanna Six" suspects is scheduled to plead guilty Monday afternoon before U.S. District Judge William M. Skretny.
Federal prosecutors saidMukhtar al-Bakri, 23, will take a felony plea at 2 p.m. Monday.
Members of al-Bakri's family in Lackawanna also confirmed the plea deal, saying al-Bakri had agonized over his decision. His attorney, John J. Molloy, said he and his client had discussed the issue several times in recent weeks.
If he cooperates fully with the investigation by the Western New York Joint Terrorism Task Force, al-Bakri is likely to face a prison term of roughly 10 years, court sources said.
"The punishment is bigger than the crime," said Ahmed al-Bakri, one of the defendant's brothers.
Al-Bakri and fellow Lackawanna residents Yasein Taher, Faysal Galab, Shafal Mosed, Yahya Goba and Sahim Alwan were arrested in September on charges that they provided material support to a terrorist organization by training at an al-Qaida camp in Afghanistan in 2001.
All six have admitted they trained at the camp, but all have denied they intended to engage in violence against the United States. Al-Bakri's five co-defendants have taken plea deals.
FBI agents said the six men learned how to use weapons and a grenade launcher at the camp, heard a speech from terrorist leader Osama bin Laden and then kept the information a secret after returning to Lackawanna.
