Iran’s critical energy infrastructure at the South Pars gas field came under drone attack, with multiple gas treatment facilities in Asaluyeh reportedly damaged in a major escalation. State media said four key plants were hit, forcing operations offline to control fires and prevent further spread, raising concerns over potential disruption to gas production. South Pars, the world’s largest natural gas reservoir shared with Qatar, plays a crucial role in global energy supply, and any impact on its output could have far-reaching consequences.
