A grand jury today indicted a 26-year-old Massachusetts man who is accused of plotting to attack the Capitol and Pentagon.

Rezwan Ferdaus was arrested Wednesday. A Justice Department statement announcing the arrest said he would face three charges: supporting a foreign terrorist organization, attempting to destroy national defense premises and attempting to damage and destroy U.S. buildings with an explosive.

An indictment filed today with the U.S. District Court for the District of Massachusetts shows he is also being charged with attempting to build an explosive, being in receipt explosive materials and attempting to provide material support to terrorists.

The Justice Department alleges that Ferdaus, who holds a degree in physics from Northeastern University, planned to use a team of gunmen and remote-controlled aircraft filled with explosives to attack the two government buildings. The department said in a statement that Ferdaus believed he was collaborating with representatives of al-Qaida, but he was actually in contact with undercover FBI operatives, who have been monitoring him since 2010.
