Strikes Hit Iran’s South Pars Gas Hub as Tehran Threatens Gulf Energy Retaliation

A strike on Iran’s South Pars gas-processing and refinery complex has triggered explicit Iranian threats to target named oil and gas facilities across the Gulf, with energy markets reacting immediately as infrastructure becomes the centre of the conflict.

Explosions at the Asaluyeh processing hub forced shutdowns of major gas-treatment facilities, after which Tehran issued evacuation warnings naming specific refineries and LNG terminals in Saudi Arabia, the UAE and Qatar as potential retaliation targets.

On 18 March 2026, explosions were reported across multiple installations within the South Pars Special Economic Energy Zone in Bushehr province. Iranian state media reported that airstrikes struck gas-processing units, storage tanks and petrochemical facilities in Asaluyeh, the onshore hub that processes output from the South Pars field.

The South Pars field is the largest natural gas reserve in the world and supplies more than two-thirds of Iran’s domestic gas consumption. Iranian officials stated that at least four sections of the processing system were taken offline following the strike, while two major refinery-linked processing plants with a combined capacity of roughly 100 million cubic metres per day halted operations to contain fires.

Video footage circulating online showed dense smoke rising from the coastal industrial zone, consistent with the Asaluyeh processing corridor where offshore gas is treated and distributed into Iran’s power grid and industrial network.

The strike represents the first confirmed hit on Iran’s upstream gas-processing system in the current conflict, moving beyond earlier attacks on storage depots into infrastructure central to the country’s energy supply.

Energy markets reacted immediately. Brent crude rose between 4% and 5% on the day, trading between 107.95 dollars and nearly 109 dollars per barrel. This extended a broader surge that has already pushed oil prices more than 40% higher since the conflict began in late February.

European natural gas prices also climbed by approximately 6.6%, reflecting concern that disruption to South Pars could affect regional processing capacity and downstream supply.

Within hours of the strike, Iran issued direct and specific retaliation warnings. Statements carried by Iranian state media and repeated across international reporting identified a list of Gulf energy facilities described as potential targets.

These included:

• Saudi Arabia: Ras Tanura refinery, Samref refinery, and Jubail petrochemical complex
• United Arab Emirates: Al Hosn gas field and key export terminals
• Qatar: Ras Laffan LNG complex and Mesaieed industrial zone

Iranian Revolutionary Guard messaging warned that these sites should be evacuated, describing them as legitimate targets following the strike on South Pars.

The language marked a shift from general deterrence to explicit operational signalling. Iranian officials framed the response as direct equivalence, indicating that attacks on Iranian energy infrastructure would be met with strikes on comparable oil and gas assets across the region.

Iran-aligned media reinforced this position. Al Manar TV reported that retaliation would extend beyond Israel to include United States-linked assets across the Gulf, while Press TV described the response under an “eye for an eye” doctrine in which energy infrastructure becomes a central target category once Iranian facilities are hit.

Iran’s retaliation is not limited to threats. Since 28 February, Iranian forces have carried out more than twenty confirmed attacks on commercial shipping in the Strait of Hormuz using drones, missiles and explosive boats.

These attacks have resulted in vessel fires, abandonments and casualties among crews. Maritime traffic through the Strait, which normally carries around one-fifth of global oil supply, has fallen sharply as operators divert or delay shipments due to the security environment.

Iran has not declared a total closure of the Strait but has instead applied selective restrictions. Officials have indicated that vessels linked to the United States, Israel and allied states may be denied passage, while traffic associated with non-aligned countries has in some cases been permitted.

The pattern of escalation is now clear. Initial missile exchanges have been followed by sustained attacks on shipping and, after the South Pars strike, explicit threats to energy infrastructure across the Gulf.

Earlier in the conflict, drone activity targeting Saudi Arabia’s Ras Tanura refinery caused fires and temporary disruption, establishing a precedent for energy infrastructure being drawn into the conflict.

At the time of reporting, there are no independently verified confirmations that the specific Gulf facilities named in Iranian warnings have been struck following the South Pars attack. The retaliation remains declared and partially executed through maritime disruption rather than confirmed large-scale refinery strikes.

The situation has entered a new phase defined by energy systems. The strike on South Pars has disrupted Iran’s core gas-processing network, while Iran’s response has explicitly expanded the target set to include oil refineries, LNG terminals and petrochemical complexes across the Gulf.

Further escalation will depend on whether Iran moves from declared intent to confirmed strikes on the named facilities. The specificity of the warnings, combined with ongoing disruption in the Strait of Hormuz, indicates that energy infrastructure is now the central battleground of the conflict.
