Why has the US halted its bombing of Iran? Tit-for-tat strikes have halted in the Middle East amid reports of depleted US weapons stocks. The United States paused strikes on Iran on Friday after nearly two weeks of bombardments, including in the Strait of Hormuz, since the Islamabad-brokered ceasefire unravelled.

Washington has not carried out attacks targeting Iran, preventing Tehran’s retaliatory attacks on US military assets and infrastructure in countries in the region. Although US President Donald Trump has denied it, media reports there said Washington may be running low on air defence interceptors, while pressure is mounting on both sides to give diplomacy another chance amid heightened stakes. Here’s what we know about why the US has halted its attacks and what is happening in diplomatic channels.

What is the situation now? Despite the sudden lull in the exchange of strikes, the Strait of Hormuz – the critical waterway that has emerged as one of the biggest flashpoints in this war – remains closed. Iran’s state broadcaster IRIB reported that six ships had attempted to pass through an “illegal and unsafe” route in the south of the Strait of Hormuz in the early hours of Monday after turning off their navigation and positioning systems.

One vessel suffered an unspecified accident, IRIB said, while the others returned to the Gulf under “decisive Iranian management”. It quoted an official who blamed the US military for “provoking” the ships to sail on the unauthorised route. However, retaliatory attacks by Iran on US military assets and infrastructure in Bahrain, Kuwait and Jordan have ceased.

“Our strategy has essentially been retaliatory. We have also halted our retaliatory operations,” said Iranian army spokesman Mohammad Akraminia. Global oil prices dropped by about 4 percent after the US and Iran halted exchanging missiles, signalling a potential shift towards diplomacy.

On Saturday, the US military said its naval blockade of Iranian ports, including those in the Strait of Hormuz, “remains in full effect”, but did not specify why Washington had halted attacks on Iran after 13 nights of escalating strikes. What tensions remain? The biggest flashpoint and the issue which directly caused the resumption of strikes two weeks ago is the Strait of Hormuz, which Iran effectively closed to international shipping shortly after the US and Israel began attacks on Tehran on February 28.

Iran has been discussing proposals with Oman, whose territorial waters also extend into the strait, to reopen the Strait of Hormuz under a shared management protocol. However, it is not clear if that would be acceptable to Trump, or the Gulf Cooperation Council (GCC) countries. Following the signing of a memorandum of understanding (MoU) between the US and Iran on June 17, the strait was supposed to be open and free to shipping traffic for a minimum of 60 days while peace talks were under way.

However, the two sides disagreed on who had ultimate control over shipping routes and which path ships should take. That resulted in Iranian attacks on ships taking the “wrong” routes and, ultimately, Trump’s resumption of strikes on Iran.
