Mohamud then suggested to the two undercover agents that he detonate a bomb during the annual Christmas tree lighting ceremony, according to the affidavit. When the FBI agents suggested that Mohamud would have to use a car bomb, and might also have to die during the operation, Mohamud said he was willing, alleges the affidavit. Mohamud also allegedly determined where to park a van filled with explosives in the city square.
Mohamud told the agent that he sought a "huge mass that will…be attacked in their own element with their families celebrating the holidays."
On Friday, when the FBI loaded a van with a fake device, they asked Mohamud to detonate the fake bomb by dialing a number on a cellphone. After he failed to explode the device with his first call, alleges the affidavit, he dialed the number a second time and FBI agents swooped in to arrest him.
On Monday, Mohamud's attorney said he planned to use an entrapment defense.
