A 26-year-old Massachusetts man has been arrested and accused of plotting to destroy the Pentagon and the U.S. Capitol with large remote-controlled aircraft filled with explosives.

Rezwan Ferdaus of Ashland was arrested Wednesday in Framingham when undercover federal agents delivered materials he'd requested for his alleged plan, including grenades, six machine guns and what Ferdaus believed was C-4 explosive.

Ferdaus, a U.S. citizen and graduate of Boston's Northeastern University, was scheduled to appear in federal court in Worcester (WUS'-tur) on Wednesday afternoon.

A message for comment was left for his attorney, Catherine Byrne.

According to the federal affidavit, Ferdaus began planning "jihad" against the U.S. in early 2010. He allegedly believed he would have a large psychological impact by killing Americans, whom he described as "enemies of Allah."
