South Pars gas field struck — world's largest natural gas reservoir hit as energy war escalates

The South Pars natural gas field in the Persian Gulf — the world's largest gas reservoir — was struck on Day 19, marking the most economically consequential energy infrastructure attack of the war. Qatar, which shares the field with Iran, blamed Israel. Iran's South Pars side supplies roughly 75% of its domestic gas output and the bulk of its LNG exports. The strike follows escalating mutual energy targeting: Iran has been hitting Gulf Arab oil and gas facilities throughout the war, while Israel and the US have targeted Iranian military and energy infrastructure. With oil already above 108 dollars per barrel, up 40% since the war began, disruption to South Pars production threatens further severe global energy price shocks.
