An Israeli drone strike on Irans South Pars gas field—the worlds largest—has triggered a serious energy disruption and widened the conflict. The fire damaged one of the processing units in Phase 14, halting 12 million cubic metres of gas output.

"This confrontation will not end with last night's limited actions and Iran's strikes will continue, and this action will be very painful and regrettable for the aggressors," Fars reported, citing senior military officials.
