A sharp escalation between the United States, Israel and Iran entered a third day, as strikes and counterstrikes rippled across the region and markets signalled rising alarm. Israeli forces said they have mobilised roughly 110,000 reservists and fired some 2,500 munitions since the campaign began, while Iran launched multiple ballistic-missile and drone counterattacks and declared it is prepared for a long war.
Tehran reported explosions in several districts, including near the defence ministry, and large detonations were heard around Isfahan, where key air bases and nuclear-related facilities are located. The Islamic Revolutionary Guard Corps (IRGC) said it had carried out the 13th round of its "Real Promise-4" operations, firing Khorramshahr-class ballistic missiles at targets it identified in Tel Aviv, Haifa and East Jerusalem; Israeli authorities denied some of those specific damage claims.
The United States has been openly involved in the strikes and in the subsequent fight over airspace. U.S. Central Command said it had attacked numerous targets in Iran and that six American service members had died; the Pentagon reported that three F-15E fighters were shot down near Kuwait after they were mistakenly engaged by Kuwaiti air defences, though Tehran separately claimed responsibility for downing the aircraft. Washington has also signalled that "the heaviest blows are yet to come," and President Trump reiterated objectives to degrade Iran's missile and naval capabilities and to prevent a nuclear breakout.
The confrontation has already spilled beyond Iran–Israel lines. Israel opened a second front against Lebanon, conducting strikes across the country against Hezbollah positions after the group launched precision rockets and drones at Israeli sites. Beirut's government has moved to distance the state from Hezbollah by banning armed activity by the militia and ordering it to surrender weapons; the Lebanese health ministry reported dozens killed and many more injured in Israeli air raids.
A particularly consequential development is Iran's announcement—via a senior IRGC adviser—that the Strait of Hormuz is closed to transit, and that Tehran will attack vessels attempting to pass. International shippers and insurers reacted quickly: major operators halted transits through the waterway, and trading in oil and gas surged. Brent crude spiked nearly 13% intraday, European gas benchmarks jumped more than 50% at one point, and equity markets opened lower as investors priced heightened supply risk.
Fog and friction have characterised the battlefield. Both sides advance contested casualty and damage tallies, while reports of senior Iranian intelligence losses and the death of a close relative of Iran's supreme leader circulated alongside denials and competing narratives. U.S. military officials say no U.S. ground forces have entered Iran, but they caution that more air assets will join the campaign in coming days, leaving the possibility of further escalation open.
The immediate international consequences are economic and strategic: interruptions to shipping through Hormuz threaten global energy flows and add inflationary pressure to already fragile markets, while fighting across Lebanon increases the risk of a broader regional conflagration. Major external powers face a choice between supporting de-escalatory diplomacy and reinforcing military postures that could entrench the conflict and widen its human and economic toll.
Uncertainty is the most reliable feature of the hours ahead. Commanders, capitals and markets are all reacting to rapid developments amid competing claims and limited independent verification. The clash has moved beyond episodic tit‑for‑tat exchanges into a sustained, multi-front confrontation that could persist for weeks or months unless diplomatic channels, regional third parties or a costly operational pause intervene.
