Iran War: IRGC and Ansar Allah Fire Away At Tankers, Oil Facilities, Airports

The attacks targeted both energy shipping and infrastructure. The IRGC claimed it hit a giant liquefied petroleum gas carrier using an unauthorized route south of Hormuz. Ansar Allah struck additional Saudi oil facilities, while airport attacks on Thursday disrupted civilian aviation. Together, these actions widened the conflict’s immediate economic effects.

The IRGC said the tanker suffered a large engine-room fire. Another vessel, Dhalkut, reported nearby shooting off Fujairah. Airlines cancelled all flights to Saudi Arabia after the airport attacks. Kpler reported that tanker attacks pushed oil exports sharply lower, while Reuters reported only seven commodity vessels crossed on October 6.

The immediate result was less movement through and around the Gulf. Seven vessels crossed on Tuesday, compared with more than 20 daily on October 4 and 5. Crude flows fell to at least 10.1 million barrels per day, or 74 percent of the prewar level. Further attacks could deepen shipping and aviation disruption.

The IRGC, or Islamic Revolutionary Guard Corps, is Iran’s military-security organization and a central instrument of Tehran’s regional power. Ansar Allah is the movement commonly known as the Houthis, which controls significant territory in Yemen. The article places both within a wider confrontation involving Iran, Saudi-backed forces, the United States, and Israel.

Their roles differ by arena. The IRGC directly threatened and attacked tankers near Hormuz and beyond it. Ansar Allah attacked Saudi oil facilities and was involved in the Yemen fighting around Bab al-Mandeb and Mocha. Saudi-backed forces claimed advances, while Ansar Allah denied those claims.

Together, their actions create pressure across connected energy routes. Iran can threaten Gulf shipping, while Ansar Allah can target Saudi infrastructure and routes near Yemen. The article also reports continuing Saudi bombing in Yemen. This coordination or parallel pressure makes the conflict’s effects regional rather than confined to one battlefield.

The Strait of Hormuz is a narrow waterway between Iran and Oman that connects the Persian Gulf with the Gulf of Oman and the Arabian Sea. It is a major chokepoint because large volumes of oil and gas leave Gulf-producing states through this passage. Any threat there can affect energy markets far beyond the region.

The article shows why control and access matter. Iran said vessels using an unauthorized route would be pursued throughout the region. Tankers sometimes wait at Fujairah, outside the Gulf, for cargoes shuttled out from inside it. That arrangement reflects the strait’s importance and the need to manage exposure to attacks.

When the route becomes dangerous, operators slow or stop voyages, reroute ships, or wait offshore. The article reports that seven commodity vessels crossed on October 6, compared with more than 20 daily on October 4 and 5. Such a sharp fall can reduce exports and increase pressure on buyers and shippers.

The article gives several benchmarks rather than one single normal figure. Kpler reported a September flow of around 15.5 million barrels per day, while the seven-day average through October 7 was 9.9 million barrels per day. That average was 42 percent below the stated prewar baseline.

Crude flows through the strait reached at least 10.1 million barrels per day during the reported period. This was 27 percent below the previous wartime high and equal to 74 percent of the prewar level. Vessel movements also weakened sharply: only seven commodity vessels crossed on October 6.

The comparison with earlier days shows the speed of the decline. More than 20 commodity vessels crossed daily on October 4 and 5, but the number fell to 10 on October 7 after reaching seven on October 6. The figures show attacks affecting both physical shipping traffic and the amount of crude exported.

When attacks make a major maritime route unsafe, ships may avoid it, wait outside the danger zone, or require armed protection. Fewer voyages mean fewer barrels reach buyers on schedule. Scarcity and uncertainty can raise freight rates, insurance premiums, and the cost of rerouting. The article directly links tanker attacks with sharply lower exports.

The reported numbers show this mechanism. Kpler said flows had recovered to prewar levels in September, but intensified tanker attacks drove exports sharply lower that week. Commodity-vessel crossings dropped to seven on October 6, compared with more than 20 daily two days earlier. Fujairah became a waiting point for more risk-averse tankers.

Air operations can suffer separately but simultaneously. The article says Thursday’s airport attacks caused many airlines to cancel all flights to Saudi Arabia. Continuing danger can therefore disrupt fuel supply chains, maritime trade, passenger travel, and schedules at once. The longer the threat lasts, the greater the pressure on exporters, importers, insurers, and carriers.

Attacking beyond Hormuz expands the danger zone. It tells Gulf states and shipping companies that cooperation with the United States may bring costs even outside the strait itself. The article quotes John Walker saying Iran wanted to remind Gulf states that the economic and security cost of supporting Washington was not confined to Hormuz.

Fujairah illustrates the logic. It had become a popular mooring place for more risk-averse tankers waiting for cargoes shuttled out of the Gulf. A nearby shooting involving Dhalkut showed that ships using this safer staging area could also face danger. The IRGC separately warned that unauthorized vessels would be pursued throughout the region.

The strategy may also dilute American protection. Walker said US jets focused on Hormuz could leave other areas more exposed. Extending attacks forces defenders to cover a wider area and makes rerouting less reliable. It can also discourage ships from waiting near Fujairah, further reducing traffic and exports.

Energy shippers can reduce dependence on Hormuz through overland pipelines, alternate export terminals, and longer sea routes. Saudi Arabia’s East-West pipeline can move some oil toward the Red Sea, while the United Arab Emirates has a pipeline route to Fujairah. Ships can also sail around Africa, although that adds distance, fuel use, and time.

These options work through different mechanisms. Pipelines bypass the contested waterway, and Fujairah provides an outlet beyond the strait. Cargoes can also be sourced from other regions, while gas, renewables, nuclear power, or efficiency can reduce oil demand over time. These are established alternatives, but the article itself specifically mentions Fujairah and cargoes shuttled out of the Gulf.

Replacement is difficult because pipeline capacity is finite, terminals cannot instantly expand, and long sea routes cost more. Many Gulf producers are built around Hormuz-connected infrastructure. Alternative energy also requires new equipment and time. The article’s sharp traffic and export declines show how quickly disruption can exceed available substitutes.
