Iran Threatens Gulf Energy Infrastructure After South Pars Strike
March 18, 2026 – Iran has warned that oil and gas infrastructure across the Persian Gulf could become “legitimate targets” following an Israeli strike on its giant South Pars gas field, escalating concerns over regional supply disruptions and global energy market volatility. The warning signals a potential shift in the conflict, raising the risk of direct attacks on critical energy infrastructure.
Escalating Tensions and Threats
The threat, conveyed through Iranian state-linked media Bloomberg, specifically names facilities in Qatar, Saudi Arabia, and the United Arab Emirates as being at heightened risk. Iranian authorities stated that five facilities – Saudi Arabia’s SAMREF refinery and Jubail petrochemical complex, the UAE’s Al Hosn gasfield, and Qatar’s Ras Laffan refinery and Mesaieed petrochemical complex and holding company – “will be targeted in the coming hours” Al Jazeera.
South Pars Gas Field Attack
The Israeli strike targeted the South Pars gas field, one of the world’s largest natural gas developments and a cornerstone of global LNG supply The New York Times. The field is shared between Iran and Qatar, making it a critical asset for both domestic consumption and export markets. While Iranian state media reported damage to a number of facilities, no casualties were immediately reported Al Jazeera.
Impact on Global Energy Markets
The attacks have already impacted global energy markets. Crude oil prices surged in response, with Brent rising above $108 per barrel, reflecting market concerns about potential prolonged outages or damage to critical infrastructure World Oil. The price of North Sea oil jumped from $103.7 a barrel to over $105 in a matter of minutes, eventually trading at $108.9 per barrel.
The gas price in Europe also experienced volatility, rising from 49 euros per megawatt hour to 55.4 euros before 3 pm.
Regional Energy Flows Disrupted
Regional energy flows are already under strain. Shipping through the Strait of Hormuz – through which roughly one-fifth of global oil and gas supply moves – has been severely disrupted, forcing production shut-ins across several Gulf producers and tightening global supply World Oil. Recent attacks have also included strikes on facilities in the United Arab Emirates and Saudi Arabia, expanding the geographic scope of the conflict.
Previous Attacks and Concerns
The South Pars strike follows a series of recent attacks affecting oil and gas production in the Middle East. These include incidents at the port of Fujairah, military targets on the Iranian island of Kharg (through which 90% of Iran’s oil exports flow), and attacks on vessels in the Strait of Hormuz and the Persian Gulf. The United Arab Emirates also temporarily closed a major oil refinery following a drone attack, and Bahrain’s energy company declared “force majeure” due to the ongoing conflict.
Long-Term Implications
Analysts warn that attacks on energy infrastructure could have long-lasting consequences. Damage to refineries, storage tanks, and production facilities may take years to repair, unlike previous disruptions that could be resolved within weeks or months. The Ras Laffan LNG plant in Qatar, for example, is expected to take up to four weeks to restart, and only after a ceasefire is in place.
