‘Mother of Satan’ bombs show foreign hand in Sri Lanka bombings

COLOMBO: One month after the Sri Lanka suicide attacks that killed more than 250 people, investigators have told AFP the bombers used “Mother of Satan” explosives favoured by the Islamic State group that are a new sign of foreign involvement. Detectives said the back-pack bombs used in the April 21 attacks on three churches and three hotels were manufactured by local jihadists with Islamic State expertise.

They named the explosive as triacetone triperoxide, or TATP, an unstable but easily made mixture favoured by Islamic State militants who call it “Mother of Satan”. It was also used in the 2015 attacks in Paris, by a suicide bomber who hit the Manchester Arena in England in 2017 and attacks on churches in Indonesia one year ago. Islamic State has claimed the Sri Lankan bombers operated as part of its franchise.

But Sri Lankan and international investigators are anxious to know just how much outside help went into the attacks that left 258 dead and 500 injured. “The group had easy access to chemicals and fertiliser to get the raw materials to make TATP,” an official involved in the investigation told AFP.

Sri Lankan detectives say the National Thowheeth Jama’ath (NTJ), local militants blamed for the attacks, must have had foreign help to assemble the bombs. “They would have had a face-to-face meeting to transfer this technology. This is not something you can do by watching a YouTube video,” said the official, speaking on condition of anonymity. Investigators had initially believed that C4 explosives — a favoured weapon of Tamil Tiger rebels — were used, but forensic tests found TATP which causes more burning than C4. Police have also confirmed that 100 kilograms (220 pounds) of explosives found in January in the island’s northwest was TATP.

They are checking the travel records of the suicide bombers as well as foreign suspects to see when and where bomb-making lessons could have been staged. “It looks like they used a cocktail of TATP and gelignite and some chemicals in the Easter attacks. They were short of the 100 kilos of raw TATP that were seized in January,” said the investigator. Sri Lankan security forces have staged a series of raids since the bombings.
