Assessment
Iran is conducting retaliatory strikes against Gulf energy infrastructure following reported Israeli attacks on its South Pars gas facilities and the killing of senior Iranian officials.
This development signifies a strong shift towards economic confrontation aimed at global energy markets, intending to exert indirect influence over Israel, the United States and its allies.
Tehran is likely to engage in decisive responses aimed at putting pressure on Washington and its regional allies in the Persian Gulf
Intelligence Requirements (IRs)
- Is Iran preparing to expand the conflict into Gulf energy infrastructure?
- Does Iran possess the capability to execute credible retaliatory strikes?
- What is the likelihood of broader regional escalation over the next phase of the conflict?
Context
- On 18 March 2026, Israeli military forces hit facilities connected to Iran’s South Pars gas field, part of the world’s largest natural gas reserve, jointly operated with Qatar. Iranian authorities stated there were no casualties, though infrastructure damage and temporary evacuations occurred.
- The escalation is concurrent with Israeli success in eliminating high-ranking Iranian figures. Tehran authorities confirmed the death of Intelligence Minister Esmail Khatib after an overnight strike, which followed the prior day’s elimination of senior security official Ali Larijani. In parallel, Israel escalated military actions against Hezbollah positions in Beirut, showing the application of pressure on multiple fronts against Iranian-aligned entities.
- In response, Tehran issued evacuation warnings to workers and residents near major energy installations in Saudi Arabia, the United Arab Emirates, and Qatar, naming specific refineries, petrochemical complexes, and gas facilities employing large workforces.
- In the last hour, Iran launched a successful and highly damaging attack on Qatar’s Ras Laffan complex.
- Energy markets experienced an immediate response, as Brent crude saw an approximate increase of 5%, reaching about $110 per barrel because of concerns about supply disruptions.
Analysis
IR1: Is Iran preparing to expand the conflict into Gulf energy infrastructure?
Highly Likely. Tehran’s warnings about evacuations appear to be deliberate pre-strike signals, aligning with previous Iranian escalation tactics. Public designation of energy facilities as legitimate targets shows an intent to broaden the conflict domain from military confrontation to economic pressure.
Tehran’s strategy shows an aim to inflict consequences that extend past the immediate conflict by jeopardising the worldwide energy security. By targeting infrastructure linked to US regional partners, Iran seeks to generate external diplomatic pressure for de-escalation while maintaining strategic initiative.
Threats and attacks towards Saudi and Qatari facilities suggest Iran prioritise war strategy over considerations for neutral economic partners, highlighting the perceived strategic significance of re-establishing deterrence credibility after leadership casualties and attacks on domestic infrastructure.
IR2: Does Iran possess the capability to execute credible retaliatory strikes?
High Capability, Moderate Confidence in sustained operations. Iran possesses a developed inventory of medium-range ballistic missiles and combat-capable unmanned aerial vehicles, which can strike energy infrastructure within the Gulf region. Previous regional operations show operational proficiency against fixed energy targets, particularly facilities concentrated along vulnerable coastal zones.
IR3: What is the likelihood of broader regional escalation?
Probable. Leadership decapitation strikes increase domestic pressure on Tehran to respond visibly. However, sending out advance alerts and messages about moving people out shows an effort to manage a situation as it gets worse, rather than just reacting with harsh punishment.
Iran’s strategy appears focused on calibrated coercion: inflicting economic uncertainty sufficient to influence international actors while avoiding thresholds that would unify regional militaries against it.
Outlook
Iran is conducting strikes targeting Gulf energy infrastructure or maritime energy logistics to reinforce deterrence credibility. The risk of disruptions to energy supplies will continue to be high, leading to ongoing price fluctuations even if physical infrastructure is not significantly damaged.
Beyond denouncing Iran’s retaliatory strikes, Gulf Arab monarchies might also get militarily involved, aligning with the United States against Iran.
