(U//FOUO) Key Findings

(U//FOUO) Individuals hoping to use homemade explosives to harm the United States and our allies remain highly motivated and innovative as the 1993 World Trade Center bombing and the thwarted Belgian terrorist attacks of 2015 reveal.

(U//FOUO) A number of extremely destructive explosive compounds such as triacetone- triperoxide (TATP), hexamethylene triperoxide diamine (HMTD), and urea nitrate can be manufactured using products available on the legitimate consumer market.

(U//FOUO) Malicious actors have used these three explosive compounds in a number of successful and thwarted attacks, meaning the following examples are not exclusive. TATP was found in a raid on a suspected Belgian safe house of a terror cell in January 2015; HMTD was used as a detonator in the London transit bombings of 7 July 2005; and lastly, urea nitrate was used in the 1993 World Trade Center Bombing.

(U//FOUO) Common materials used to manufacture one or more of these explosives include:  Hydrogen peroxide (a common hair product, disinfectant, or bleaching agent)  Acetone (commonly found in nail polish remover)  Nitric acid (a fertilizer ingredient also found in industrial waste)  Urea (commonly found in deicer or urine)

(U//FOUO) Terrorist training manuals outlining the detailed process of homemade explosives manufacturing are widely available through open sources.

(U//FOUO) Local Analysis

(U//FOUO) Indiana Code IC-35-47.5-5-2 (b) states that a person who knowingly or intentionally possesses, manufactures, transports, distributes, possesses with intent to distribute, or offers to distribute a destructive device, unless authorized by law, commits a Level 5 felony (Indiana Code, 2014).

(U//FOUO) Successful bombings using TATP, HMTD, and urea nitrate were used against critical infrastructure and transportation systems, to devastating effects.

(U//FOUO) Analyst Note: The precursor chemicals needed to manufacture the explosives TATP, HMTD, and urea nitrate are widely available throughout the Indiana legitimate consumer market. Grocery stores, big box retailers, drug stores, and chemical suppliers sell the necessary ingredients to manufacture these substances.

(U//FOUO) The majority of plants that produce nitric acid, a key ingredient in the manufacture of urea nitrate, are located in the Midwest, South Central, and Gulf States due to a high demand for fertilizers in these areas. At least four nitric acid plants are located within 250 miles of the Indianapolis area (THOMASNET.com, n.d.).

(U//FOUO) Background

(U//FOUO) Triacetone-triperoxide (TATP) was discovered by German Scientist Richard Wolffenstein in 1895. TATP, an organic peroxide based explosive, is 83% as powerful as the equivalent amount of TNT. TATP has been nicknamed “the Mother of Satan” because many terrorists and security forces have been maimed or killed while handling this highly unstable substance (Kristijan, Keinan, & Tarsi, n.d.).

(U//FOUO) Triacetone-triperoxide (TATP) in powder form. Source: (Ahura Scientific).

(U//FOUO) TATP is a highly sensitive improvised primary explosive, easily manufactured by mixing hydrogen peroxide and acetone with the addition of an acid, such as sulfuric, nitric, or hydrochloric acid (National Counterterrorism Center, n.d.). This explosive is typically found in white crystalline powder form and has a distinct smell of bleach (Perthnow, 2013).

(U//FOUO) TATP may be used as a detonator to set off more stable secondary explosives (Pyronfo, n.d.). It may also be used alone as a main explosive due to its destructive nature and high sensitivity to friction, heat, and shock.

(U//FOUO) Analyst Note: The ingredients needed to manufacture TATP are commonly produced consumer goods:  Hydrogen peroxide (a hair product, disinfectant, or bleaching agent)  Acetone (a common ingredient in nail polish remover)  An acid (such as hydrochloric acid—also known as muriatic acid—can be ordered online or found in swimming pool maintenance stores, among others) IIFC MISSION STATEMENT The mission of the Indiana Intelligence Fusion Center is to collect, evaluate, analyze and disseminate information and intelligence data regarding criminal and terrorist activity in the State of Indiana while following Fair Information Practices to ensure the rights and privacy of citizens.

(U//FOUO) TATP poses a major threat to security services and law enforcement because its ingredients don’t contain the nitrate or nitro contents found in standard explosives such as TNT, C4, and RDX; making it extremely difficult to detect using conventional methods such as metal detectors and puffer booths (Dobson, 2010; Jean, 2007).

(U//FOUO) In 2001, a terrorist attempted to detonate an explosive device containing TATP on a flight from Paris, France to Miami, Florida. Passengers and crew aboard the flight subdued the man after a flight attendant noticed he had attempted to light a protruding from his shoe with a match (CNN, 2009).

(U//FOUO) In October 2005, a college student died when the TATP he was carrying exploded outside a college football game (Johnson, n.d.).

(U//FOUO) On 15 January 2015, Belgian commandos raided the safe house of a terror cell suspected to be associated with a known terrorist organization after wiretaps of phone conversations and listening devices indicated the cell was in the final stages of planning a major terrorist attack in Belgium. Inside, Belgian police discovered the chemicals necessary to manufacture TATP, thwarting an imminent terrorist attack (Cruickshank, 2015).

(U//FOUO) Hexamethylene triperoxide diamine (HMTD) is an improvised primary explosive, typically found in powder form and often produced using three precursors: hydrogen peroxide, hexamine, and a weak acid (Johnson, n.d.; National Counterterrorism Center, n.d.).

(U//FOUO) An alternative mixture used in the production of HMTD includes a combination of formaldehyde solution, hydrogen peroxide, and ammonium sulfate (Nordin, 2005). Additional alternative ingredients exist as well. (U//FOUO) Hexamethylene triperoxide diamine (HMTD) in powder form. Source: (National Counterterrorism Center, n.d.).

(U//FOUO) Terrorist training manuals describing the detailed production method and use of HMTD are available through open sources (Interagency Threat Assessment Group (ITACG); Department of Homeland Security Office of Intelligence and Analysis (DHS I&A); Federal Bureau of Investigation Counterterrorism Analysis Section, 2009).

(U//FOUO) HMTD is highly sensitive to electrostatic discharge, impact, and friction. (National Counterterrorism Center, n.d.).

NO REPORT OR SEGMENT THEREOF MAY BE RELEASED TO ANY MEDIA SOURCES.

(U//FOUO) Analyst Note: The high sensitivity of HMTD means it can be detonated by the spark from an electric source such as a battery, the flame from a lighter or match, or the friction produced by feet walking through an HMTD laden room.

(U//FOUO) HMTD’s blast strength is estimated at 60% of the equivalent amount of TNT. Due to its destructive nature and high sensitivity, HMTD may be used as either a primary or main explosive that doesn’t acquire the assistance of a blasting cap. The danger of peroxide based explosives (such as TATP and HMTD) is not only their explosive performance but also their ease of detonation, as well as the ease in which malicious actors may acquire the materials to manufacture them (Marshal & Oxley, 2011).

(U//FOUO) The following ingredients used to manufacture HMTD can be easily acquired at local convenience stores (Interagency Threat Assessment Group (ITACG); Department of Homeland Security Office of Intelligence and Analysis (DHS I&A); Federal Bureau of Investigation Counterterrorism Analysis Section, 2009):  Citric acid (typically found in food additives, water softener, and powdered drinks)  Hexamine (often acquired through the purchase of camp stove fuel tablets)  Hydrogen peroxide (an easily purchased disinfectant or bleaching agent)

(U//FOUO) In July 2005, four suicide bombers struck central London, killing 52 people and injuring over 770 others. Three went off on underground trains and a final explosion occurred nearly an hour later on a double decker bus in Tavistock Square (BBC News, n.d.).

(U//FOUO) The four suicide bombers who carried out the London bombings used HMTD to detonate a highly potent main explosive consisting of concentrated hydrogen peroxide and black pepper (Gardham, 2007). (U//FOUO) The number 30 bus a suicide bomber destroyed (U//FOUO) The suspected terrorists purchased large in the London transit bombings of 7 July 2005 using amounts of hydrogen peroxide in the months before homemade explosives. Thirteen passengers were killed. Source: (Martin, 2011). the attacks –a key ingredient in the manufacture of HMTD and the main explosive. Vendors failed to raise concerns as to why these men were purchasing hydrogen peroxide in such large quantities (McVeigh, 2011).

(U//FOUO) Household objects, including a 9 volt battery, light bulb, wire, and aluminum foil were used to manufacture the HMTD detonator devices responsible for the 2005 London Bombings (McVeigh, 2011).

(U//FOUO) Urea nitrate is a high energy explosive compound produced by combining dissolved urea fertilizer with nitric acid (National Counterterrorism Center, n.d.). Urea nitrate is categorized as a secondary explosive, meaning it often requires a small explosive charge (such as a blasting cap, TATP, or HMTD) to detonate. However, it may also detonate without assistance if subjected to prolonged heating or contact with some other chemicals (Riddel, 2015).

(U//FOUO) Urea nitrate is favored by amateur terrorists because it is fairly easily derived from urea fertilizers or made by combining nitric and uric acids. Nitric acid can (U//FOUO) This test tube contains urea nitrate in the be acquired as waste from several industrial processes, form of a white crystalline substance. Source: while urea is a common fertilizer or driveway deicer and (Almog & S. Zitrin, 2015; National Counterterrorism Center, n.d.). can also be obtained from urine. Thus, this material provides similar explosive power to TNT at a lower comparative cost (Lucas, n.d.; Reciprocal Net, n.d.).

(U//FOUO) Nitric acid, a vital component in the manufacture of fertilizer and urea nitrate, is widely available throughout the United States. Because of a high demand for fertilizer in agricultural regions such as the Midwest, South Central, and Gulf States, a majority of the nitric acid plants in the U.S. are located in these areas. In 1991 alone, there were approximately 65 nitric acid manufacturing plants in the United States with a total capacity of 11 million tons of nitric acid production per year (Environmental Protection Agency , 1993).

(U//FOUO) In February 1993, a terrorist detonated a vehicle borne improvised explosive device (VBIED) containing between 1,200 and 1,500 pounds of urea nitrate on the second level of the parking basement below Trade Tower One in New York City with the alleged aim of knocking the North Tower (Trade Tower One) into the South Tower. The resulting blast crater was 150 feet in diameter and five floors deep. The Federal Bureau of Investigation later spoke of the VBIED used in the bombing as “the largest by weight and by damage of any improvised explosive device that we’ve seen since the inception of forensic explosive identification” (Knight, n.d.; Greenspan, 2013).

(U//FOUO) Analyst Note: Although the amount of urea nitrate used in the 1993 World Trade Center Bombing was unusually large, much smaller amounts of the explosive have been used in improvised explosive devices (IEDs) by malicious actors worldwide, to devastating effects.

(U//FOUO) IEDs are capable of causing substantial casualties and irreparable damage. These devices often contain the following components: an initiator, switch, main charge, power source, and a container. In addition, “enhancements” such as glass, nails, or metal fragments may be added to increase the number of projectiles propelled by the explosion (U.S. Department of Homeland Security, n.d.).

(U/FOUO) In May 2010, a suspected terrorist attempted to detonate a VBIED in Times Square in New York City. The vehicle used in the attempted VBIED attack contained 250 pounds of urea based fertilizer packed in a gun locker. If the fertilizer had been mixed with nitric acid, (hence creating urea nitrate) the resulting explosion would have destroyed the vehicle and caused mass casualties (West & Stewart, 2010). Two street vendors spotted smoke seeping from the parked vehicle and alerted police, foiling the attempted plot (Siemaszko, 2014).

(U//FOUO) Detection

(U//FOUO) The following materials are known ingredients for manufacturing TATP and HMTD (Johnson, n.d.):

 Hydrogen peroxide antiseptic  Hair coloring  Wood bleach  Acetone  Ethanol  Nitro methane  Sulfuric acid  Citric acid  Hexamine (solid fuel for camp stoves)

(U//FOUO) A combination of the following indicators could be evidence of explosives manufacturing (Johnson, n.d.):

 Foul odors/ caustic fumes  Paint discoloration  Metal corrosion  Structural damage  Strong chemical odors from exterior drains/sewers  Multiple fans in multiple windows  Dead vegetation  Refrigerators and coolers

(U//FOUO) Additional suspicious activity indicative of explosives manufacturing (specifically concerning urea nitrate) (J. Gilmore Childers, Esq. Orrick, Herrington & Sutcliffe LLP , 1998):

 Obtaining a storage locker or shed and utilizing it to store large amounts of the aforementioned materials  Highly frequent or unusual visits to a storage facility or shed  Calling various chemical companies to obtain known explosive materials  The delivery of bomb making materials to a storage facility or shed (possibly on multiple occasions by chemical companies). These bomb making materials may include: urea, nitric acid, sulfuric acid, ethyl alcohol, sodium carbonate, smokeless powder, potassium nitrate, methyl alcohol, aluminum metal powder, and ferric oxide.
