Iran's paramilitary Revolutionary Guard launched drone attacks targeting Bahrain and struck an oil tanker transiting the Strait of Hormuz early Saturday morning, prompting immediate U.S. military retaliation and threatening to collapse fragile ceasefire negotiations just weeks after an interim agreement was reached. The escalation underscores the fundamental challenge of negotiating with a regime that uses violence as a bargaining tool and treats international waterways as leverage rather than respecting freedom of navigation.
Bahrain said Iranian drones targeted the country in what it called a flagrant threat to the security of citizens and residents. There were no immediate reports of damage. Iran's Revolutionary Guard said in a statement carried by the state-run IRNA news agency that it had targeted several locations of the U.S. terrorist army in the region, but did not name specific areas. The attack came just after Bahrain had hosted U.S. Secretary of State Marco Rubio for a meeting of the Gulf Cooperation Council's foreign ministers, which ended with a call for an end to Iran's attacks and for the strait to be completely open.
U.S. Strikes Iranian Military Infrastructure
The U.S. military said it had struck 10 targets in Iran at President Donald Trump's direction, continuing a string of attacks that had shaken the war's uneasy ceasefire. U.S. Central Command said in a post to social media that U.S. military aircraft targeted Iranian military surveillance infrastructure, communication systems, air defense sites, drone storage facilities and minelayer capabilities after an attack on a merchant vessel early Saturday morning. The strikes involved 10 Iranian military targets at multiple locations in and near the Strait of Hormuz.
Trump said in a social media post that the U.S. had struck Iranian missile and drone storage locations and coastal radar sites for violating the Cease Fire Agreement, again. He warned that the U.S. may no longer be able to be reasonable and would be forced to militarily complete the job. He wrote on Truth Social, "If that happens, the Islamic Republic of Iran will no longer exist!"
U.S. Central Command said the latest attack involved Iranian forces attacking the oil tanker Kiku with a one-way drone. The tanker was laden with more than two million barrels of crude oil and was sailing through the Strait of Hormuz. According to ship tracking websites, the Kiku left a Qatari oil field in the middle of the Persian Gulf earlier in the week and was bound for a port in the United Arab Emirates on the Gulf of Aman, just on the other side of the Strait of Hormuz. It appeared to be attempting to use a route established near the coast of Oman that is serving as an alternative to the route sanctioned by Iran that runs through its own waters.
The Strait of Hormuz Flashpoint
A multinational maritime body overseen by the U.S. Navy said it would expand the Omani route to allow for both inbound and outbound traffic, likely setting up a new flashpoint with Tehran, which sees the strait as a key source of leverage in ongoing talks with the U.S. The U.S. military said Iran had a chance to honor the ceasefire agreement but elected not to when its forces attacked the Kiku. Iran state TV reported explosions in an area just north of the Strait of Hormuz.
The British military's United Kingdom Maritime Trade Operations center said a tanker was attacked in the strait, with the crew safe and no environmental damage reported. No one immediately claimed the strike, but suspicion fell on Iran. The Joint Maritime Information Center, overseen by the U.S. Navy, said the route near Oman's shore was expanding to allow for inbound and outbound traffic. Iran has insisted that ships must obey its orders and warned it will start charging fees for transit through the strait. The U.S. and Gulf Arab states have rejected Iran's demands. The strait is considered an international waterway, despite being the territorial waters of Iran and Oman.
The Joint Maritime Information Center warned that the threat to ships was substantial, adding that mariners are advised of the existence of mines and should expect a naval presence as clearance operations continue. The International Maritime Organization on Friday halted a new effort to evacuate ships and said it would not resume until there were guarantees that the other ships would not be attacked. It said about 115 ships had been able to move out of the strait in recent days.
Negotiations Under Pressure
The U.S. and Iran are negotiating terms of the deal including issues such as getting ships through the strait that is vital to global supplies of oil and natural gas and addressing the future of Iran's nuclear program and stockpile of highly enriched uranium. Under the interim deal, the two sides have 60 days to work out the details. Ending the fighting in Lebanon between Israel and the Iranian-backed Hezbollah militant group is a key part of the deal.
U.S. Vice President JD Vance, who has led the negotiations with Iran, said on social media Friday night that Iran should pick up the phone if there are disagreements about the ceasefire agreement, but violence will be met with violence. Bahrain has been one of the strongest critics of Iran and is home to the U.S. Navy's 5th Fleet.
Lebanon Tensions Complicate Regional Picture
Separately, the Israeli military said it carried out a drone strike in southern Lebanon, saying the target posed a threat to its forces. The strike came a day after a security deal, and Reuters reported that Hezbollah rejected the U.S.-brokered Israel-Lebanon security arrangement, describing it as surrender. Reuters also said an Iran-U.S. memorandum of understanding was being discussed as a potential framework for ending the conflict.
Why This Matters:
Iran's repeated violations of the ceasefire agreement reveal the fundamental challenge of negotiating with a regime that views agreements as tactical pauses rather than binding commitments. The targeting of commercial shipping through the Strait of Hormuz—a waterway vital to global oil and natural gas supplies—demonstrates Iran's willingness to hold the international economy hostage to advance its regional ambitions. The simultaneous rejection by Hezbollah, Iran's most powerful proxy, of a U.S.-brokered security arrangement in Lebanon shows Tehran's strategy of using militant groups to maintain pressure on Israel while negotiating with the United States. The expansion of alternative shipping routes near Oman's coast represents a practical response to Iranian threats, but also creates new potential flashpoints as Iran insists on controlling transit through what international law recognizes as international waters. The presence of mines in the strait and the substantial threat to mariners underscore the security vacuum created when a revisionist power is allowed to challenge freedom of navigation. If the interim agreement collapses, the region faces the prospect of either sustained military confrontation or acceptance of Iranian dominance over critical maritime chokepoints—neither of which serves long-term stability or the security interests of U.S. allies in the Gulf.
