While the investigation into the attacks in Brussels this week continues, one thing seemed certain from the outset -- the weapons used, three bombs, were familiar ones.
The Islamic State of Iraq and the Levant claimed responsibility for the separate blasts that killed 31 and injured 270 Tuesday. Even before publicly saying they were behind the bombings, authorities suspected ISIS was involved when police in Brussels recovered explosive-making materials at the apartment of one of the suspected bombers.
The materials – peroxide and acetone – are the ingredients for the terror organization’s signature weapon – the “mother of Satan” explosive.
Here’s a quick look at what the explosive is, what it does and why they use it.
What is it?
The explosive – called the "Mother of Satan" because of its volatility and the capacity for extreme damage – has been for some time the weapon of choice for terrorists. According to a story from The Washington Post, it is a weapon not seen in a battlefield situation, but used extensively by ISIS and other terror organizations. When processed, the explosive, triacetone triperoxide or TATP, is a white, powdery substance that is odorless. The explosive is triggered by heat or friction.
The solid produces a large amount of gas on ignition, but doesn't necessarily produce fire. The acetone can ignite causing a fire.
How is it made?
Concentrated peroxide and acetone, among other ingredients, are used to produce TATP. The combined chemicals are highly unstable, and create a potent blast. A very small amount can produce enough energy to blow someone’s hand off.
Why can’t it be found by bomb detectors and the person carrying it stopped?
There is no nitrogen in TATP, thus its presence would not register with nitrogen bomb detectors. The chemicals are common ones found in everyday items.
Why do they use it?
Convenience, mainly. The ingredients are easy to find and purchase, allowing bomb makers to gather what’s needed without necessarily attracting attention. TATP, along with hexamethylene triperoxide diamine -- HMTD -- has been used by terrorists for some time. The “shoe bomber,” Richard Reid, tried to ignite TATP on a Christmas Day flight from Paris to Miami in 2001. Terror groups began using the explosive some 20 years ago.
