What happened

A storage tank at a clean-energy company within the Ningdong Energy Chemical Industry Base caught fire around 9am and was extinguished about ninety minutes later. Four of the eight construction workers present were later found dead, while the other four were evacuated safely. The cause was under investigation and not established in the cited reporting; the pattern is consistent with a hot-work failure during tank work. This was an accidental industrial incident, not an attack.

When cited sources give different casualty, damage or spill figures for this event, they’re reported side by side above rather than merged into one number. See how confidence levels work.
