the government ordered port officials put under house arrest amid speculation that negligence was to blame. The investigation is focusing on how 2,750 tons of ammonium nitrate, a highly explosive chemical used in fertilizers, came to be stored at the facility for six years, and why nothing was done about it. Fueling speculation that negligence was to blame for the accident, an official letter circulating online showed the head of the customs department had warned that the huge stockpile of ammonium nitrate stored in a hangar in the port was a danger, and asked judicial officials for a ruling on a way to remove it. It had been confiscated from a ship in 2013.
