Chemicals and other components found in the Bench apartment of Fazliddin Kurbanov could have been used to manufacture improvised explosive devices, federal prosecutors claim in new court filings.
Mixing together stocks of potassium nitrate, sulfur and charcoal found in in Kurbanov’s apartment on South Curtis Road in November 2012 could have produced 13 pounds of an explosive mixture commonly used in IEDs, explosives examiner Christopher Rigopoulos of the FBI is prepared to testify, according to the filing.
Prosecutors say a metal hand grenade body and fuses found at the apartment could have been used along with the explosive to create an IED.
Police also seized ammonium nitrate pellets coated with aluminum powder. By itself, ammonium nitrate, a common fertilizer, is not explosive. Combined with other chemicals, it can become explosive. Ammonium nitrate was used by Oklahoma City bomber Timothy McVeigh in 1995.
Kurbanov, who is charged in Boise with conspiracy to provide material support to a foreign terrorist organization, conspiracy to provide material support to terrorists, attempting to provide that support and possession of an unregistered explosive device, is set to go on trial July 13.
The trial had been scheduled to begin May 5, but was delayed to allow lawyers on both sides more time to prepare.
Kurbanov also was indicted by a federal grand jury in Salt Lake City of one count of distributing information related to explosives, destructive devices and weapons of mass destruction. That case has been placed on hold while the Idaho charges move forward.
Authorities accuse Kurbanov of planning an attack in the United States.
Authorities say that in August 2012, Kurbanov began communicating online with a person associated with the Islamic Movement of Uzbekistan, a terrorist organization whose aim is to overthrow the Uzbek government and create an Islamic state.
“We need to know how to connect the wires, how much and what to do,” Kurbanov wrote. “Also it would be great if we learn how to operate the remotely controlled ones.”
In January 2013, Kurbanov became friends with a confidential FBI informant. During a 10-day period, Kurbanov showed the informant bomb-making videos and discussed different ways to make bombs, the FBI said. In one recorded conversation in English, the informant asked Kurbanov the best target.
“For me, the best ... a military base,” Kurbanov said, according to earlier filings. “If I have every stuff ... like bomb, like this and this one. I want to kill a lot of military or every, I don't know, whatever.”
