A Liberian oil tanker made its way out of the Strait of Hormuz yesterday despite threats to shipping from Iran’s paramilitary Revolutionary Guard, using a new route close to Oman’s shore that has been promoted by a U.N. maritime agency.

The transit of the Stoic Warrior and the threats come as tensions rise between Iran and the United States over the terms of their interim accord aimed at permanently ending the Iran war.

From getting ships through the narrow mouth of the Persian Gulf to the future of Iran’s stockpile of highly enriched uranium, the two nations are increasingly debating the terms of the deal signed last week.

Through the signing of the memorandum of understanding, the U.S. and Iran agreed to a 60-day period to iron out these and other details. Until that happens — during private talks — leaders from both countries will also continue to negotiate in public, raising the risks of derailing the shaky ceasefire in the region.

On a trip to the Middle East, U.S. Secretary of State Marco Rubio spoke Thursday with Gulf Arab officials in Bahrain, the island kingdom in the Persian Gulf home to the Navy’s 5th Fleet, trying to assuage their concerns.

The flareup of fighting in Lebanon between Israel and the Iranian-backed militia Hezbollah has threatened the deal. On Wednesday, Israel launched an airstrike that killed two people in southern Lebanon, the country’s state-run news agency said. It was Israel’s first airstrike on Lebanon since the latest ceasefire took effect on Saturday.

Tanker sails through Strait of Hormuz

The Stoic Warrior — signaling that it planned to transit the Strait of Hormuz — took off early Thursday morning along the coast of the United Arab Emirates and then Oman.

The vessel then traveled around Oman’s Musandam Peninsula fairly close to the shore, part of a route that Oman laid out alongside the International Maritime Organization, an agency of the United Nations that oversees shipping at sea.

North of the route is the Traffic Separation Scheme, the route in the center of the strait that for decades ships moved through freely. The route is used for transport of about a fifth of all the world’s oil and natural gas.

However, there has been the report of at least one mine sighted in the water after the Guard said that it mined the passage during the war that started on Feb. 28 with U.S. and Israeli strikes on Iran. The threat of mines shut off the route.

Even before the deal, some ships had been getting out of the strait, with U.S. military support. But the U.N. agency’s effort is the latest to free trapped vessels. The shipping company Maersk said Thursday that its container ship the Maersk Baltimore and another chartered vessel had also made it out the strait.

The naval arm of the Revolutionary Guard, apparently reacting to the new IMO’s route, issued an angry warning Thursday, carried by Iran’s 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 said.

“It is hereby notified to all that the only authorized route for passing through the Strait of Hormuz is the one declared by the Islamic Republic of Iran,” the Iranian force said. “Vessel traffic outside these routes is extremely dangerous and prohibited.” By JON GAMBRELL & MATTHEW LEE, DUBAI, MDT/AP
