Rezwan Ferdaus, of Ashland, pleaded guilty Friday to attempting to provide material support to terrorists and attempting to damage and destroy federal buildings by means of an explosive.
The 26-year-old was arrested last year after federal employees posing as al-Qaida members delivered materials he requested, including grenades, machine guns and plastic explosives.
Under a plea agreement, federal prosecutors agreed to drop four other charges. Prosecutors and Ferdaus’ lawyers also agreed to request a 17-year sentence on charges that carry a combined maximum of 35 years in prison.
Ferdaus grew up in Massachusetts and has a physics degree from Boston’s Northeastern University.
