US-Iran Ceasefire Strains as Strikes Erupt and Gulf Tensions Rise

The US-Iran ceasefire faced fresh strain after new American strikes and Iranian retaliation. Washington said Iran broke the truce first. Tehran said the US air operation breached the agreement. Missiles and drones later targeted US-linked sites in Kuwait and Bahrain. The exchange raised concern about a wider Gulf conflict.

US President Donald Trump said US forces hit Iranian missile and drone storage sites. Trump also cited strikes on coastal radar positions. Trump described the attack as a response to repeated ceasefire violations. In the same message, Trump issued a direct warning about future US action.

On Truth Social, Trump wrote, "United States aircraft just struck Iranian missile and drone storage locations, and coastal radar sites, for violating the Cease Fire Agreement, AGAIN! It is very possible that they will never learn! There may come a point when we are no longer able to be reasonable, and will be forced to militarily complete the job that we very successfully started. If that happens, the Islamic Republic of Iran will no longer exist! President DJT."

US Central Command later said Navy and Air Force jets hit 10 Iranian military targets. The military listed systems linked to surveillance and communications. It also cited air defence positions, drone storage, and minelayers. The US said the action followed an alleged Iranian strike near Hormuz.

According to the US military, Iran attacked the Singapore-flagged container vessel M/T Kiku. The incident was reported near the Strait of Hormuz. US officials said this violated the ceasefire terms. Washington then linked its strikes to that alleged attack.

Iran’s Islamic Revolutionary Guard Corps said it launched missiles and drones in response. The IRGC said naval and aerospace units coordinated the operation. The stated targets were US military sites in Kuwait and Bahrain. Tehran said American strikes violated the ceasefire arrangement.

In a statement carried by Press TV, the IRGC said, "Violating the ceasefire is contrary to Clause 1 of the Islamabad Memorandum of Understanding and will result in the complete halt of all diplomatic processes."

Kuwait said its forces responded to incoming missiles and drones. The Kuwaiti military said air defences were intercepting hostile projectiles. In Bahrain, air raid sirens sounded near a major US naval base. Authorities advised residents to stay calm and move to safe locations.

US-Iran ceasefire: Hormuz warnings and diplomatic claims

Iranian officials warned of further action if fighting continued. Ibrahim al-Fiqar spoke for Khatam al-Anbiya Central Headquarters. Al-Fiqar said Iran would tighten oversight of Strait of Hormuz traffic. Al-Fiqar posted, "Any new aggression, regardless of its pretext or the scale of its objectives, will be met with a crushing response. Violating the ceasefire constitutes a breach of Article 1 of the Islamabad Understanding and will lead to a complete halt of all tracks. Under the Islamabad understanding, Iran will regulate maritime traffic in the Strait of Hormuz. Violent vessels will be dealt with more firmly than before."

Iran also warned Gulf states hosting US facilities. Tehran said American bases would "experience hell in these days." Iran’s foreign ministry called the US strikes "an explicit violation of the first paragraph of the Memorandum of Understanding" signed this month. US Vice President JD Vance said, "If they have disagreements about how the MOU is being applied, they can pick up the phone. But violence will be met with violence."

Reports also mentioned explosions in Iran’s Sirik region and on Qeshm Island. Those reports came earlier on June 27, 2026. The events added to instability across Gulf waterways and coastlines. Both sides continued trading military claims and ceasefire accusations. The truce remained in place, but appeared increasingly fragile.
