  • A car exploded near the Red Fort Metro Station in Delhi on November 10, 2025.
  • Investigators suspect that, the car might be carrying Ammonium Nitrate Fuel Oil (ANFO).
  • ANFO is a common industrial explosive made by mixing porous ammonium nitrate with fuel oil.
  • Ammonium nitrate is an odourless, white crystalline chemical that is commonly used to make fertiliser and explosives.
  • It is a powerful oxidiser and, under the right conditions, can cause a massive explosion that involves the rapid decomposition of the chemical compound into a large volume of hot gases.
  • The decomposition reaction from an ammonium nitrate bomb produces an exothermic reaction, releasing nitrous oxide and water vapour.
  • They can expand rapidly (up to 1,000 times the initial volume).
  • The reaction also generates significant heat, with temperatures reaching up to 2,000 degrees Celsius in the immediate vicinity.
  • But on its own, ammonium nitrate is not considered an explosive.
