Gulf Tensions: Iran Bars Navy Entry as Brent Crude Hits $117

Brent crude reached approximately $117 per barrel on Saturday, marking its highest level since April, as tensions escalated in the Persian Gulf. The price spike followed a declaration by Ali Abdollahi, the chief of general staff of Iran's armed forces, that United States naval vessels are prohibited from re-entering Iranian territorial waters or their immediate surroundings. Abdollahi stated that Iranian forces are prepared to target any vessel in the region, effectively closing the strategic waterway to American military traffic.

The military directive came in direct response to comments made by President Donald Trump during a rally in Florida on Friday. Trump indicated that the United States had not yet decided on its next strategic move in the ongoing conflict. He suggested the military "may do another Epic Fury," referencing the large-scale bombing campaign launched against Iran at the start of the war in February. The President previously weighed the option of ending the fighting with massive strikes against allowing the naval blockade and sanctions to continue squeezing Tehran's economy.

Abdollahi criticized American rhetoric as contradictory in a statement carried by state media. He argued that while Washington claims Iran's military capabilities have been largely destroyed, it has refused to move aircraft carriers and support ships closer to Iranian territory. He described the US position as allowing its soldiers to only "dream" of entering the Persian Gulf again. The Iranian general also framed the conflict as a response to the surprise attack on February 28, which initiated an eight-month war and unsettled the region. He stated that Iranian forces intend to "drown" the United States and Israel in a "quagmire."

Shipping activity around the Strait of Hormuz remains under frequent attack. The Islamic Revolutionary Guard Corps reported that seven tankers were attacked or hit mines overnight into Thursday. On Friday, the IRGC claimed that two supertankers struck mines. The group said its military doctrine has shifted toward a more offensive posture. In response to the heightened risk, Washington has reportedly ordered many diplomatic staff to leave Saudi Arabia, with additional personnel due to depart from other countries in the region.

The conflict has expanded to other fronts in the Middle East. The Iran-allied Houthis in Yemen struck Riyadh on Saturday, following recent attacks on Dammam's international airport and the Shaybah oilfield. Saudi forces responded by bombing Houthi-held areas, including Marib and Taiz. In southern Lebanon, Israeli air strikes hit the area around Nabatieh, and artillery fire fell near Zawtar ash-Sharqiyah. In the West Bank, Israeli Prime Minister Benjamin Netanyahu ordered a lockdown after a Palestinian attack killed two soldiers in Hebron. Netanyahu faces a general election on October 27.

Diplomatic efforts to resolve the crisis have stalled. Senior diplomats from Turkiye, Saudi Arabia, Pakistan, and Egypt met with counterparts from the UK, France, Germany, and Italy in Istanbul on Friday. The United States and Iran were not present at the talks. Turkiye's Foreign Minister Hakan Fidan said a new attack on Iran "would widen the war and spread the conflict across the region." He added that "no one is endorsing it at this point." German Foreign Minister Johann Wadephul blamed Iran and the Houthis for regional instability, while the four regional ministers stated that "Israeli occupation was the main source of instability." They backed the Islamabad memorandum of understanding signed in June and demanded unrestricted passage through Hormuz.

Iranian state-linked media and analysts claim Tehran has activated a "dead hand" doctrine. This alleged protocol would allow attacks on US, Israeli, and regional interests to continue from all 31 provinces if senior leaders are assassinated again. The IRGC has also threatened seabed internet and communication cables if civilian infrastructure is targeted once more. According to Axios, which cited US intelligence, Iran has "substantially increased" efforts to strike American officials in the Middle East and elsewhere. Reformist newspaper Etemad suggested the "zero hour" of another intense round of fighting was approaching, while analyst Reza Nasri wrote on X that Iran "will no longer negotiate under bombardment."
