DUBAI, United Arab Emirates — The U.S. launched strikes on Iran early Tuesday, hours after President Donald Trump vowed to reinstate an American blockade of Iranian ports and charge ships for safe passage through the Strait of Hormuz. Iran responded with attacks on Middle East allies of the U.S.
The latest exchange of fire leaves in tatters an interim deal meant to pause the fighting, reopen a waterway that is key to world energy supplies and give negotiators time to hammer out a permanent end to the war. Instead, fighting has once again engulfed the region, threatened the global economy and brought warnings to commercial airlines. Unless a diplomatic solution is found quickly, it could intensify into all-out war.
The focus of the conflict now is the strait, through which a fifth of all traded crude oil and natural gas passed in peacetime. Iran effectively shut the passage during the war by attacking and threatening ships - a tactic that proved its greatest strategic advantage. It sent the price of oil, fertilizer and other goods soaring at a time when world leaders were already struggling to address rising costs.
The interim deal was supposed to reopen the waterway, but Iran has attacked ships moving through the strait on a route overseen by the U.S. military that is outside Tehran’s control.
The U.S. has now threatened to reopen the strait by force - but experts say that will require a much bigger armada if not tens of thousands of American ground troops. It’s possible Trump will back down, as he has previously.
Attacks resume across the Mideast
The U.S. military’s Central Command said it struck several areas in Iran, targeting “coastal defense systems, missile and drone sites and maritime capabilities.” Iran acknowledged the strikes but provided no immediate casualty or damage assessments.
“These strikes will continue imposing a heavy cost on Iranian forces and degrade their ability to attack innocent civilians and commercial shipping in the Strait of Hormuz,” the U.S. military said.
Iran responded with attacks targeting Bahrain, Jordan and three tankers that traveled through the strait.
Two of the ships were associated with the United Arab Emirates and were set ablaze for a time. The Emirati Defense Ministry said the attack on the tankers Mombasa and Al Bahiyah killed one mariner and wounded eight others. The Emirates threatened to retaliate.
Dutch shipping firm Stolt Tankers said that one of its ships came under attack. The attack on the Stolt Magnesium off Oman sparked a fire in the engine room, but the company said all the mariners were safe.
Iran’s paramilitary Revolutionary Guard claimed the attack on the Mombasa and Al Bahiyah, saying the vessels “ignored repeated warnings.” Iran has targeted ships that use a route through the strait that passes near Oman outside of its territorial waters.
Hours after the U.S. said it ended its campaign of strikes, the Iranian city of Bushehr on the Persian Gulf was hit in at least four locations, the state-run IRNA news agency reported. It again raised the possibility that Gulf Arab states were attacking Iran in retaliation.
Bahrain, home to the U.S. Navy’s 5th Fleet, sounded its missile alert sirens three times early Tuesday, urging people to seek shelter. Jordan’s military said it intercepted four missiles from Iran. Jordan hosts U.S. forces and has come under attack by Tehran in recent days.
The European Union Aviation Safety Agency warned airlines against operating in the airspace of Bahrain, Kuwait, Qatar and the United Arab Emirates, as well as over the Gulf of Oman.
It said in a bulletin that “unpredictable military developments, combined with the possible use of missiles, drones, combat aircraft and air-defense systems, create a high risk to civil flights.”
Interim deal is in peril
Exchanges of fire in recent days had already cast doubt on the interim peace deal - now almost halfway through the 60-day period in which negotiators were supposed to agree to a final accord, which also was meant to address Iran’s disputed nuclear program and other issues.
But Trump’s vow to impose a blockade further imperils it. Washington lifted a blockade it imposed in mid-April as part of the deal. The U.S. military said it will resume it at midnight in Dubai.
“We are reinstating the THE IRANIAN BLOCKADE,” Trump said on social media Monday.
He said the U.S. would impose a fee for protecting other ships: 20% of the value of cargo to help cover “any and all costs necessary to do the job of providing safety and security.”
That’s a change to longstanding U.S. policy. The U.S. Navy has fought for freedom of navigation on the seas since the Barbary Wars in the early 19th century and the War of 1812. It’s also a departure from recent U.S. promises that the strait would remain open to all without tolls - recently offered by U.S. Secretary of State Marco Rubio on a trip to the region.
Under the interim deal, Iran agreed that passage through the strait would remain free of charge for 60 days - but the agreement left open what would happen after. Iran asserts it has the right to manage traffic through the strait and potentially charge fees. The U.S. has disputed that.
Any attempt by the U.S. or Iran to charge fees would violate global norms on freedom of navigation and raise tensions, likely causing further economic disruption far beyond the region.
The price of Brent crude oil, the international standard, rose to a one-month high of over $87 in trading Tuesday, still well below the nearly $120 reached at the height of the war but threatening to make costs everywhere higher.
Negotiations between Israel and Lebanon will resume
Lebanese and Israeli delegations were expected to meet in Rome on Tuesday to continue U.S.-mediated negotiations. Shortly after the U.S. and Israel launched the war on Feb. 28, the Lebanese militant group Hezbollah joined the conflict in support of its ally, Iran, and began attacking Israel. Israel responded with a ground invasion of Lebanon.
Last month, Lebanon and Israel announced a “framework agreement” outlining the withdrawal of Israeli forces from southern Lebanon in exchange for the disarmament of Hezbollah. Implementation has stalled.
Before the fighting around the strait intensified, Israel’s war against Hezbollah in Lebanon repeatedly threatened to derail the interim deal. A truce now exists in Lebanon, but it remains unclear whether it will hold if the U.S. and Iran return to full-scale war.
