What happened

Unsafe operation of a crude-oil transport truck during a period of heavy traffic sparked a fire that spread to storage tanks at Iran's second-largest refinery (over 300,000 bbl/d capacity), causing two of five neighboring tanks to explode; eight firefighters suffered minor injuries and the blaze was extinguished within about three hours with no other casualties reported. This was an accidental industrial incident, not an attack. (Note: an earlier, less-documented claim of a June 2022 Bandar Abbas fire could not be independently verified; this entry reflects the well-sourced July 2023 event.)

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.
