What Happened
- Israel, in coordination with the United States, struck Iran's South Pars gas field — the world's largest natural gas field — targeting Phases 3, 4, 5, and 6; Iran shut down those phases to contain the resulting fires.
- This marked the first time Israel had targeted Iran's natural gas infrastructure, representing a significant escalation of the conflict into energy warfare.
- Iran killed three senior Israeli officials on the same day in separate strikes; Iran's leadership stated these assassinations would not destabilise the country's political structure.
- Iran threatened to strike five named energy facilities across Gulf states: Saudi Arabia's SAMREF refinery and Jubail petrochemical complex, UAE's Al Hosn gasfield, and Qatar's Ras Laffan refinery and Mesaieed complex.
- Iran subsequently followed through with missile strikes on Qatar's Ras Laffan Industrial City, causing extensive damage to the world's largest LNG production facility.
- West Texas Intermediate crude surged to $98.60 per barrel; European gas benchmarks jumped 6% following the attacks.

South Pars/North Dome: The World's Largest Gas Field
The South Pars/North Dome gas-condensate field is the largest known natural gas reservoir in the world, straddling the maritime boundary between Iran (South Pars) and Qatar (North Dome) in the Persian Gulf. The field is of enormous strategic importance to both nations and, by extension, to global energy markets.
- Total area: approximately 9,700 sq km — 3,700 sq km (South Pars, Iran) + 6,000 sq km (North Dome, Qatar).
- Estimated reserves: 1,800 trillion cubic feet of in-situ gas and approximately 50 billion barrels of gas condensates.
- South Pars accounts for 36% of Iran's total proven gas reserves and 5.6% of world proven gas reserves.
- The North Dome (Qatar's section) accounts for nearly 99% of Qatar's proven gas reserves and about 14% of world proven gas reserves.
- South Pars supplies approximately 75% of Iran's domestic gas needs, with daily production exceeding 700 million cubic metres.
- The field is developed in phases (Iran has 24+ phases); each phase has offshore gas platforms and onshore processing at Assaluyeh/Bushehr.
Connection to this news: Striking South Pars was aimed at degrading Iran's most critical energy and economic asset; the attack on Phases 3-6 directly curtailed both domestic gas supply and export capacity, and triggered Iran's retaliatory strikes on Gulf energy infrastructure.
Energy Warfare and Economic Coercion in Modern Conflicts
Energy warfare refers to the deliberate targeting of an adversary's energy production and distribution infrastructure to achieve strategic objectives without necessarily defeating its armed forces. In the Middle East, energy infrastructure has been a recurring target due to its dual role — generating national revenue and sustaining civilian and industrial life.
- The 1991 Gulf War saw Iraqi forces set ablaze approximately 700 Kuwaiti oil wells.
- Yemen's Houthi attacks on Saudi Aramco's Abqaiq and Khurais facilities in September 2019 temporarily knocked out approximately 5% of global oil supply.
- UNSC Resolution 2140 (2014) and later resolutions condemn attacks on Yemeni energy infrastructure; similar norms exist under the Laws of Armed Conflict (Geneva Conventions Additional Protocol I, Article 54) prohibiting attacks on civilian objects.
- Iran's South Pars provides gas for electricity generation, petrochemicals, and LNG exports — making strikes on it a compound economic and strategic blow.
Connection to this news: The Israeli strike on South Pars and Iran's retaliatory strikes on Gulf facilities mark a qualitative escalation in the current conflict — transforming a political-military confrontation into direct energy warfare with global economic consequences.
Iran's Role in Global Energy Markets
Iran holds the world's second-largest proven natural gas reserves and the fourth-largest proven oil reserves. Despite being under extensive Western sanctions since 2012 (and intensified after the US withdrawal from the JCPOA in 2018), Iran remains a significant energy player in Asia.
- Iran's proven oil reserves: approximately 208.6 billion barrels (BP Statistical Review 2023), or about 12.9% of world total.
- Iran's proven gas reserves: approximately 34.0 trillion cubic metres (tcm), second only to Russia.
- Iran's oil production was approximately 3.0-3.2 million b/d in 2023-24 following easing of enforcement.
- Iran primarily exports to China under informal arrangements that circumvent US secondary sanctions.
- The Joint Comprehensive Plan of Action (JCPOA, 2015) sought to limit Iran's nuclear enrichment in exchange for sanctions relief; the US withdrew from the deal in May 2018 under the Trump administration.
Connection to this news: Attacks on South Pars directly threaten Iran's ability to export LNG and condensates — reducing its already sanctions-constrained revenue — while triggering market volatility that harms energy-importing nations including India.
