Press release from the U.S. Department of Justice:

A 26-year-old Ashland man was arrested in Framingham and charged today in connection with his plot to damage or destroy the Pentagon and U.S. Capitol, using large remote-controlled aircraft filled with C-4 plastic explosives.

Rezwan Ferdaus, a U.S. citizen, was also charged with attempting to provide material support and resources to a foreign terrorist organization, specifically to al Qaeda, in order to carry out attacks on U.S. soldiers stationed overseas.

In June, Ferdaus rented a storage facility in Framingham, under a false name, to use to build his attack planes and maintain all his equipment.

According to the affidavit, in August 2011, the F-86 remote controlled aircraft was delivered to the Framingham storage facility. Ferdaus delivered a total of eight detonation devices to the undercover FBI employees over the course of the investigation, which he built with the intention that they be used by al Qaeda operatives overseas to kill U.S. soldiers.

“Our top priority is to protect our nation from terrorism and national security threats. The conduct alleged today shows that Mr. Ferdaus had long planned to commit violent acts against our country, including attacks on the Pentagon and our nation’s Capitol. Thanks to the diligence of the FBI and our many other law enforcement partners, that plan was thwarted,” said U.S. Attorney Carmen M. Ortiz.

The public was never in danger from the explosive devices, which were controlled by undercover FBI employees. The defendant was closely monitored as his alleged plot developed and the undercover FBI employees were in frequent contact with him.

Richard DesLauriers, special agent in charge of the FBI’s Boston Division said, “Today’s arrest was the culmination of an investigation forged through strong relationships among various Massachusetts law enforcement agencies to detect, deter, and prevent terrorism.

Each of the more than 30 federal, state, and local agencies on the FBI’s Joint Terrorism Task Force worked together to protect the community from this threat. In this particular investigation, the Worcester, Ashland and Framingham Police departments and the Bureau of Alcohol, Tobacco, Firearms and Explosives, played particularly critical roles.

The communities of Worcester, Ashland and Framingham should be proud of the unwavering commitment and professionalism the agencies demonstrated in ensuring that their towns and region were safe from harm. The Massachusetts State Police and the Commonwealth Fusion Center also contributed significantly to this investigation.”

“The FBI used an undercover operation to conduct this investigation. Undercover operations are used to combat all types of crimes and criminals, including in the counterterrorism arena.”

The affidavit alleges the following: Ferdaus, a Northeastern University graduate with a degree in physics, began planning to commit a violent jihad against the U.S. in early 2010. He obtained mobile phones, each of which he modified to act as an electrical switch for an IED. He then supplied the phones to FBI undercover agents, who he believed to be members of, or recruiters for, al Qaeda.

According to the affidavit, Ferdaus believed the devices would be used to kill American soldiers overseas. During a June 2011 meeting, he appeared gratified when he was told that his first phone detonation device had killed three U.S. soldiers and injured four or five others in Iraq. Ferdaus responded, “That was exactly what I wanted.”

According to the affidavit, after each subsequent delivery, Ferdaus was anxious to know how well each of his detonation devices had worked and how many Americans they had killed.

During recorded conversations, Ferdaus stated that he devised the idea of attacking the Pentagon long before he met with the government’s cooperating witness and undercover agents, and that his jihad had, “started last year.”

In recorded conversations with the CW that began in January, Ferdaus stated that he planned to attack the Pentagon using aircraft similar to “small drone airplanes” filled with explosives and guided by GPS equipment. According to the affidavit, in April, Ferdaus expanded his plan to include an attack on the U.S. Capitol. In May and June, Ferdaus delivered two thumb drives to the agents, which contained detailed attack plans with step-by-step instructions as to how he planned to attack the Pentagon and Capitol.

The plans included using three remote controlled aircraft and six people, including himself whom he described as an “amir,” i.e., an Arabic term meaning leader.

During various recorded meetings, Ferdaus envisioned causing a large “psychological” impact by killing Americans, including women and children, who he referred to as “enemies of Allah.” According to the affidavit, Ferdaus’ desire to attack the United States is so strong that he confided, “I just can't stop; there is no other choice for me.”

In May, Ferdaus traveled from Boston to Washington, D.C., conducted surveillance and took photographs of his targets (Pentagon and Capitol), and identified and photographed sites at the East Potomac Park from which he planned to launch his aircraft filled with explosives. Upon his return, Ferdaus told the agents that “more stuff ha[d] to be done,” that his plan needed to be expanded, and that he had decided to couple his “aerial assault” plan with a “ground directive.”

Ferdaus indicated that his ground assault plan would involve the use of six people, armed with automatic firearms and divided into two teams. Ferdaus described his expanded attack as follows: ... with this aerial assault, we can effectively eliminate key locations of the P-building then we can add to it in order to take out everything else and leave one area only as a squeeze where the individuals will be isolated, they’ll be vulnerable and we can dominate.

Once isolated, Ferdaus planned to “open up on them” and “keep firing” to create “chaos” and “take out” everyone. He also provided the expanded plan to the UC on a thumb drive.

Between May and September, Ferdaus researched, ordered and acquired the necessary components for his attack plans, including one remote controlled aircraft (F-86 Sabre).

This morning, prior to his arrest, Ferdaus received from the agents, 25 pounds of what he believed to be C-4 explosives, six fully-automatic AK-47 assault rifles (machine guns) and grenades.

On Sept. 20, Ferdaus made a training video, which he provided to the agents, demonstrating how to make “cell phone detonators.”

After inspecting the components, Ferdaus brought them to his storage unit, took possession of the explosives and firearms, and locked them in his storage unit. Ferdaus was then immediately arrested.

If convicted Ferdaus faces up to 15 years in prison on the material support and resources to a foreign terrorist organization charge; up to 20 years in prison on the charge of attempting to destroy national defense premises; and a five year minimum mandatory in prison and up to 20 years on the charge of attempting to damage and destroy buildings that are owned by the United States, by using an explosive. On each charge Ferdaus also faces up to three years of supervised release and a $250,000 fine.

The case is being prosecuted by Assistant U.S. Attorneys B. Stephanie Siegmann and Donald L. Cabell of Ortiz’s Anti-Terrorism and National Security Unit.
