What happened

A fire at Sinochem's Quanzhou refinery in Fujian province led the company to shut its No. 1 crude unit (240,000 bpd capacity) at the 300,000 bpd plant. Witnesses reported thick black smoke visible for kilometers. The cause was not established in the cited reporting; the pattern is consistent with a maintenance or equipment failure. 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.
