US and Iran trade strikes as ceasefire comes under renewed strain

What Happened

On Wednesday and Thursday, the United States and Iran exchanged military strikes, severely straining a fragile April ceasefire. The US launched precision strikes on Iranian military infrastructure, targeting surveillance, communications, and air defence systems. US Central Command confirmed that Marine Corps, Air Force, and Navy assets struck areas including Bandar Abbas, Qeshm, Minab, Karaj, Nazarabad, and Pishva, with Iranian media reporting at least three wounded. The attacks followed the downing of a US helicopter near the Strait of Hormuz and accusations by President Trump that Iran was prolonging negotiations. Defense Secretary Hegseth indicated Washington might 'negotiate with bombs.' Iran’s Foreign Ministry condemned the strikes as rendering the ceasefire 'practically meaningless.' The Islamic Revolutionary Guard Corps (IRGC) retaliated by launching drones and ballistic missiles at US-linked targets in Bahrain, Kuwait, and Jordan, including the US Fifth Fleet in Bahrain, Kuwaiti airbases, and the al-Azraq airbase in Jordan. Bahrain issued air raid alerts, Kuwait temporarily closed its airspace and activated air defences, and Jordan reported intercepting 20 missiles near Azraq with no casualties, though the IRGC claimed 12 missiles hit the al-Azraq base, destroying facilities and aircraft—claims unverified. Concurrently, US forces struck shipping in the Gulf of Oman, hitting an Iranian cargo barge near Khasab and disabling three tankers, leading to the deaths of three seafarers, including two Indian crew members on the Palau-flagged Settebello. Iranian media reported that the Iranian navy hit two ships attempting to transit the strait, but US Central Command denied any halt in commercial traffic. Oil prices rose and Gulf stock markets dipped. Qatari negotiators visited Tehran but left without a reported breakthrough, while UN officials warned against a return to 'full war.'

Key Actors

Why It Matters

This direct exchange of strikes across multiple theatres—Iranian territory, Gulf states, and key maritime chokepoints—marks the most serious rupture of the April ceasefire and risks spiralling into a broader regional war. The involvement of Bahrain, Kuwait, and Jordan as targets of Iranian retaliation extends the conflict beyond a bilateral US-Iran confrontation, testing Gulf alliances and air defence capacities. Strikes on commercial shipping in the Gulf of Oman and the Strait of Hormuz disrupt vital energy transit routes, spiking oil prices and threatening global supply chains, while civilian seafarer casualties add a humanitarian dimension. The US posture of coercive diplomacy ('negotiate with bombs') coupled with Iran's resolve to retaliate against US-linked assets in the Arab world undermines ceasefire architecture and could draw in Hezbollah or other Axis of Resistance elements, especially given Iran's linkage of a settlement to a truce in Lebanon.

Watch For

Immediate indicators of further escalation: whether the ceasefire formally collapses and full-scale hostilities resume across all fronts; Iranian or IRGC follow-up strikes on US bases in the Gulf or Israel; US military responses, including additional strikes on Iranian territory or shipping; the efficacy of Qatari and other backchannel mediation efforts; UN Security Council reactions and potential emergency sessions; impacts on oil markets and Gulf financial stability; verification of IRGC claims regarding al-Azraq base damage; and any Hezbollah or Iraqi militia responses, particularly given Iran's demand for a Lebanon ceasefire as part of any agreement.
