Iran Strikes U.S. Bases in Bahrain and Kuwait, Threatens to Halt Ceasefire Talks

Iran’s Islamic Revolutionary Guard Corps launched retaliatory strikes against U.S. military installations in Bahrain and Kuwait on Wednesday and threatened to walk away from the ceasefire negotiations that have so far contained the wider Iran–United States conflict, according to NPR and PBS NewsHour.

The strikes came hours after the United States bombed Iranian facilities at Sirik, Qeshm Island, and Bandar Abbas in response to IRGC attacks on three commercial ships in the Strait of Hormuz the previous day. The exchange marks the most significant escalation since the Islamabad Memorandum of Understanding was signed June 17 — and it is unfolding on Day 22 of the agreement’s 60-day negotiating window.

What Iran Targeted

In a statement, the IRGC said it had struck 85 U.S. military sites across Kuwait and Bahrain. Specifically named targets included Bandar Salman and the Fifth Naval Fleet District in Bahrain, and Ali Al-Salem Air Base in Kuwait. Missile alerts sounded in both countries. There were no immediate reports of U.S. or coalition casualties from either government.

The 5th Fleet, headquartered in Manama, Bahrain, serves as the primary U.S. naval command for the Persian Gulf, Red Sea, Arabian Sea, and adjacent waters. Ali Al-Salem Air Base in Kuwait hosts U.S. Army forces and has served as a logistics hub throughout the conflict.

The Escalation Sequence

The events of July 7–8 trace back to a dispute over which shipping lane vessels may use through the Strait of Hormuz. Tehran has insisted since the MOU was signed that commercial ships must follow a northern route under Iranian administrative control. The U.S. Navy has been escorting vessels along a southern corridor hugging Oman’s coast.

On Monday night, the IRGC fired projectiles at the Qatari-owned LNG carrier Al Rekayat and the Saudi-flagged supertanker Wedyan as both transited the strait using the U.S.-protected route. A third vessel was struck within 24 hours, according to the Joint Maritime Information Center, a U.S.-led naval monitoring group. The Al Rekayat suffered an engine-room fire; no casualties were reported, with crew members confirmed safe and mustered on the starboard side of the vessel, according to an audio recording obtained by the Wall Street Journal.

The United States responded with airstrikes on Iranian territory and then revoked the Treasury Department license that had authorized limited Iranian oil sales on international markets. That waiver — originally set to remain in force until August 21 — was a concrete economic incentive embedded in the MOU framework. Its revocation means all pre-war sanctions are back in effect as of July 7, according to CNBC.

Iran’s Diplomatic Response

Mohammad Bagher Ghalibaf, Iran’s lead negotiator and parliament speaker, accused Washington of committing multiple “major violations” of the MOU. In remarks published by Iranian state media and reported by Republic World, Ghalibaf cited the U.S. airstrikes, what he called persistent threats of further military action, the reimposition of oil sanctions, and Washington’s failure to restrain continued Israeli military operations in Lebanon — a commitment Iran contends was implied by the MOU.

“The era of bullying and extortion is over,” Ghalibaf said. Iran’s joint military command said its armed forces would deliver a “crushing response” to what it termed a “blatant act of aggression.”

Tehran separately threatened a “complete halt” to negotiations, according to CBS News. A Washington official, speaking on background to CBS News, said the United States intended to continue talks regardless.

A contradictory signal emerged from inside the Iranian government itself: the IRGC declared the Strait closed to all vessel traffic, citing Israel’s strikes in Lebanon as a “blatant breach” of the agreement. Iran’s Foreign Ministry contradicted the military within hours, telling Tasnim News Agency that shipping was “operating normally.” The divergence between Iran’s hardline military command and its diplomatic corps has recurred throughout the conflict.

The MOU’s 60-Day Framework

The Islamabad MOU, signed June 17, established a negotiating window covering freedom of navigation in the Strait of Hormuz, Iran’s nuclear and missile programs, sanctions relief, and Iran’s regional military posture. Eight of its 14 points remain disputed or unimplemented. On the nuclear question, Iran reaffirmed in the agreement that it would not develop nuclear weapons and agreed in principle to IAEA supervision of uranium downblending — but Iran has maintained that inspectors will be admitted only after a final deal is reached, a position the IAEA has publicly contested.

The route dispute in Hormuz was never resolved in the MOU text, leaving a structural gap that the July 7 attacks exploited. The Lebanon issue, which Tehran has elevated as a test of U.S. good faith, also lacks any enforcement mechanism in the agreement.

Oil Markets

Brent crude rose approximately 5.5 percent on Tuesday following the tanker attacks and sanctions revocation, trading near $76 per barrel for September delivery, according to NBC News. The move unwound weeks of price declines driven by OPEC+ production increases and expectations that Hormuz would remain open under the MOU.

What Comes Next

The 60-day MOU window runs until August 16. Whether Wednesday’s military exchange represents a functional collapse of the ceasefire or a brief escalatory episode will become clearer in the hours ahead. Key indicators to watch: whether Iran follows through on its threat to halt talks, whether U.S. officials signal any willingness to restore the oil-sales waiver in exchange for resumed negotiation, and whether the IRGC attacks any additional vessels in the Strait. A widening allied rift visible at the NATO Ankara summit adds another complicating layer to Washington’s diplomatic position.
