Mother of Satan in Delhi car blast? Officers say TATP needs no detonator, can explode from heat; bomber Umar knew this before entering the crowded area

Investigators are increasingly suspecting triacetone triperoxide (TATP), dubbed 'Mother of Satan,' in Monday's car blast near Red Fort. This highly unstable explosive, potentially mixed with ammonium nitrate and fuel oil, could have caused the immense blast. The victim, Dr. Umar Un Nabi, reportedly had IED assembly experience, raising questions about the explosion's trigger.
