Lavan Island refinery — attack, fire and Shidvar oil spill

What happened

An attack struck the Lavan Island refinery hours after a ceasefire announcement, causing a fire that remained visible in satellite imagery two days later. Iran's refining company acknowledged the attack, but responsibility was not independently established. Geolocated mobile footage and high-resolution satellite images showed oil spreading from Lavan toward nearby Shidvar—also called Maroo—Island, coating wildlife and shoreline around a Ramsar-listed seabird and turtle habitat. Public reporting did not provide a measured release volume, cleanup status or precise pre-attack operating rate, so no full-shutdown percentage is assigned.
