Peace negotiations between the United States (US) and Iran have reportedly reached a standstill after the US military launched retaliatory airstrikes against multiple Iranian military targets. The operation was carried out in response to Tehran's renewed attacks on commercial vessels traveling through the strategically important Strait of Hormuz.

According to CNBC on Monday (June 29, 2026), aircraft from the US Central Command (CentCom) struck ten military targets located in and around the Strait of Hormuz on Sunday. The air campaign targeted military surveillance infrastructure, communication networks, air defense systems, drone storage facilities, and Iran's naval mine warfare capabilities.

Washington authorized the military operation after the Panama-flagged commercial tanker M/T Kiku, carrying more than two million barrels of crude oil, was hit by an Iranian drone while passing through the strait on Saturday. CentCom also reported that Iran had opened fire on the Singapore-flagged cargo vessel Ever Lovely off the coast of Oman on Thursday, although the ship was able to continue its voyage without interruption.

In response to the US airstrikes on its coastal facilities, Iran launched ballistic missiles and drones at several US military bases in Kuwait and Bahrain on Sunday night. Kuwait's armed forces confirmed that their air defense systems were actively intercepting incoming missiles, while Bahrain's Ministry of Foreign Affairs strongly condemned the attacks.

In an official statement, Bahraini authorities argued that Tehran's actions were neither isolated incidents nor momentary reactions, but rather part of a deliberate and systematic pattern of recurring aggression.

The exchange of attacks prompted strong condemnation from neighboring Gulf countries. The United Arab Emirates and Qatar described Iran's actions as a serious violation of national sovereignty and international law. Saudi Arabia likewise denounced Iran's aggression, emphasizing the threat it posed to regional security and the freedom of international navigation through the Strait of Hormuz.

The escalating conflict also triggered a forceful response from US President Donald Trump, who again warned that Iran could face complete destruction if the peace framework continued to be violated. Writing on his Truth Social platform, Trump said that US forces had targeted Iranian missile bases because Tehran had once again breached the ceasefire agreement. He warned that if diplomacy continued to fail, the United States would be compelled to complete its military mission, adding that the Islamic Republic of Iran could ultimately cease to exist.

Trump's latest remarks added to a series of previous warnings directed at Iran. In April, he suggested that an all-out nuclear conflict could result in the destruction of civilization overnight. In May, he further warned that Iran's time was running out and claimed that nothing would remain if the situation continued to deteriorate.

Uncertainty Surrounding the Swiss Negotiations

The latest military confrontation erupted just one week after Trump and Iranian President Masoud Pezeshkian signed a Memorandum of Understanding (MOU) intended to establish a framework for a permanent peace agreement following months of open warfare. Under the 60-day ceasefire arrangement, both sides were expected to refrain from military action. However, each government now accuses the other of violating the agreement first, including the US strike on Friday, which Washington said was prompted by alleged Iranian violations.

A Pakistani diplomatic source involved in the mediation process stated that although negotiations have been temporarily suspended because of the renewed hostilities, all delegations remain in Switzerland. Their continued presence is intended to allow talks to resume immediately once approval is granted by their respective governments. The source did not specify which side first decided to pause the negotiations.

Meanwhile, a senior official in the Trump administration rejected reports claiming that the peace talks had been unilaterally canceled. The White House maintained that technical discussions regarding implementation of the Memorandum of Understanding remain on schedule.

The official emphasized that no part of the process had been canceled and that technical consultations on implementing the agreement would continue over the coming days as originally planned.

Axios also reported that the United States and Iran had in fact reached an understanding to halt attacks at sea and were planning to hold direct talks later in the week. Despite ongoing political uncertainty, CentCom confirmed that commercial tanker traffic through the Strait of Hormuz continues to operate normally, with an increasing number of vessels successfully transiting the waterway and easing concerns over global energy supplies.

These developments affected international energy markets. Brent crude oil for August delivery closed down 4.34% at US$71.99 (approximately Rp1.28 million) per barrel on Friday. Meanwhile, US West Texas Intermediate (WTI) crude for August delivery declined 3.74% to US$69.23 (approximately Rp1.2 million) per barrel, marking the first time WTI settled below the US$70 level since February 27, one day before the outbreak of the Iran war.
