A Liberian oil tanker, the Stoic Warrior, transited the Strait of Hormuz on Thursday, proceeding along a new route near Oman's coast despite warnings from Iran's Revolutionary Guard. The tanker's passage occurred as tensions escalate between Iran and the United States regarding the terms of a recently signed interim accord aimed at permanently ending the Iran war.

The two nations have a 60-day period to finalize details of the agreement, during which both public and private negotiations will continue. This delicate process carries the risk of disrupting the fragile ceasefire in the region.

A significant factor threatening the accord is the renewed fighting in Lebanon between Israel and the Iranian-backed militia Hezbollah. On Wednesday, Israel conducted an airstrike in southern Lebanon that resulted in two fatalities, marking the first such strike since the latest ceasefire took effect on Saturday.

The Stoic Warrior departed early Thursday morning, hugging the coastlines of the United Arab Emirates and Oman before navigating around Oman’s Musandam Peninsula. This path aligns with a route proposed by the International Maritime Organization, a United Nations agency overseeing maritime traffic.

This new route diverges from the traditional Traffic Separation Scheme, the central channel of the strait that has historically facilitated the transport of approximately one-fifth of the world's oil and natural gas. Reports of at least one mine sighting in the water emerged after the Revolutionary Guard claimed to have mined the passage during the conflict that began Feb. 28 with U.S. and Israeli strikes on Iran. The presence of mines had previously halted traffic.

Reacting to the new route, the naval arm of Iran's Revolutionary Guard issued a warning through the state-run IRNA news agency. "A few hours ago, without notice or coordination with the Islamic Republic of Iran, some authorities announced a new route for ship traffic in the Strait of Hormuz, which is unacceptable and completely dangerous," the Guard stated. The force asserted that "the only authorized route for passing through the Strait of Hormuz is the one declared by the Islamic Republic of Iran" and that "vessel traffic outside these routes is extremely dangerous and prohibited." The statement added that "violators will be dealt with."

No immediate incidents were reported as the Stoic Warrior passed through the strait, with several other ships following its path, according to ship-tracking data.

Anwar Gargash, a senior Emirati diplomat, cautioned Iran against impeding maritime traffic or imposing fees on vessels in the Strait of Hormuz. "New geopolitical facts cannot be imposed on the Arab Gulf states as a result of a treacherous aggression against them," Gargash wrote on X. "It sows new seeds of discord and conflict for the future. And this is precisely what applies to the Strait of Hormuz."

In Lebanon, the Israeli military reported on Thursday that a reservist soldier was killed and another injured in southern Lebanon, where Israeli troops are operating. At least 37 soldiers have been killed in Lebanon or northern Israel since the current conflict began in March, along with one civilian defense contractor. Two civilians in northern Israel have also died.

Lebanon has seen over 4,000 people killed in Israeli strikes since the conflict with Hezbollah commenced two days after the Iran war began, when the militant group fired on Israel. Iran advocates for an end to the fighting in Lebanon and for Israel to relinquish occupied territories to achieve a permanent Mideast war deal with the U.S. Israel maintains its need for operational freedom to counter Hezbollah attacks, even as U.S. pressure on its campaign increases.
