What Happened
The United States said it completed a new wave of strikes against Iranian military targets on Tuesday, September 1, after a month in which there had been no reported direct military action between the two countries.
U.S. Central Command said American forces began striking Islamic Revolutionary Guard Corps targets in Iran at noon Eastern Time. In a statement posted at 6:33 p.m. Eastern Time, CENTCOM said the operation had been completed.
CENTCOM said the targets included air-defence sites, radar systems, maritime assets and facilities, mine-laying capabilities, and communications sites. It did not identify the locations struck, the weapons used, the scale of damage, or whether Iranian military personnel were killed or injured.
The U.S. military said the operation followed what it described as attempted IRGC attacks against commercial shipping in the Strait of Hormuz and against U.S. service members deployed in the Middle East. Those alleged attempted attacks were cited by CENTCOM as the reason for the strikes; the available sources did not independently establish their full circumstances.
Iran responded with missile and drone operations, according to Iranian state and semiofficial media cited by The Associated Press. Jordan’s military said it intercepted 10 Iranian missiles, while three others landed in unpopulated areas. The Iranian Revolutionary Guard said it had targeted a U.S. base on Jordan’s Gulf of Aqaba coast.
The reported exchange followed U.S. strikes on Iranian rocket launchers on Larak Island on August 30. CENTCOM said those launchers were being prepared to fire rockets carrying sea mines into the Strait of Hormuz. Iran subsequently said it had attacked U.S.-linked targets in Jordan, while Jordan reported intercepting missiles over its territory.
Iranian officials also reported civilian casualties from Tuesday’s U.S. strikes. Ahmad Nafisi, Hormozgan province’s deputy governor, told Iranian state television that a strike hit a home hosting a wedding in Kuhestak, in southern Iran, killing five people, including a child, and wounding at least 68 others. CENTCOM said it was aware of the reports but noted that they originated with Iranian state media; a spokesperson said the U.S. military does not target civilians.
The casualty claim could not be independently verified before the reporting cutoff.
What Is Confirmed
CENTCOM publicly confirmed that U.S. forces began strikes in Iran at noon Eastern Time on September 1 and that the wave of strikes had concluded by early evening.
The U.S. military identified the targets as IRGC-associated military infrastructure, including radar, air-defence, maritime, mine-laying and communications capabilities. Its statements did not provide a battle-damage assessment or name individual sites.
The Associated Press independently reported explosions in several southern Iranian coastal areas, including Bandar Abbas and Qeshm Island. Witnesses in Bandar Abbas told AP that explosions on September 1 appeared stronger than those reported during the preceding U.S. strikes.
Jordan confirmed that its air defences intercepted missiles that entered its airspace. It said three missiles landed in unpopulated areas. No injuries at U.S. facilities in Jordan were reported by the Jordanian military in the material reviewed.
The latest fighting occurred amid disruption to the Strait of Hormuz, the narrow waterway between Iran and Oman. AP reported that roughly one-fifth of globally traded oil moved through the strait in peacetime. The agency said traffic has been reduced sharply since the wider conflict began in late February.
AP also reported that the British military’s United Kingdom Maritime Trade Operations centre received reports of two tanker incidents near the strait on September 1. The centre reported that one tanker was struck by three projectiles while leaving the Persian Gulf. No party had claimed responsibility by the reporting cutoff.
What Remains Unclear
The number of people killed or injured in Iran, and the precise sites hit, remain unclear. Iranian state television reported strikes on civilian facilities, including a fishmeal factory on Qeshm Island, a fishing pier, a maritime authority tower and an airport near Jiroft. CENTCOM did not release location-by-location information that would allow those accounts to be assessed independently.
The reported strike on the Kuhestak wedding home and its casualty toll had not been independently confirmed. The U.S. military disputed any suggestion that it deliberately targeted civilians but did not provide further details about the reported incident.
Iran’s claimed retaliatory operations also remained only partly verifiable. Iran said it launched a drone attack against U.S. forces in Bahrain, but AP reported no immediate confirmation from Bahrain. Kuwait’s army said its air defences intercepted drone attacks, without establishing their launch point or intended targets.
CENTCOM’s assertion that the strikes followed attempted Iranian attacks on commercial shipping and U.S. personnel is an official U.S. account. The available reporting did not independently establish the timing, location, method or intended targets of those alleged attempts.
Iran and the United States also offer conflicting accounts of conditions in the Strait of Hormuz. Tehran says it retains an effective closure of the waterway, while U.S. officials have said ships are moving under American military protection. Commercial shipping remains exposed to risk, but the available evidence does not resolve either side’s broader claim of operational control.
The Wider Context
The September 1 strikes marked another deterioration after a short pause in a conflict that has lasted more than six months.
According to AP, U.S. and Israeli attacks on Iran began on February 28. Iran subsequently asserted control over access to the Strait of Hormuz, a route central to oil and other trade between the Persian Gulf and international markets. Disruption to traffic through the strait has contributed to higher energy prices and uncertainty for importers, shipping companies and insurers.
AP reported that crude prices had risen about 7 per cent during the week before September 1 and more than 50 per cent during 2026. It also cited AAA data showing the U.S. average price for regular gasoline at US$4.10 per gallon, compared with US$3.19 a year earlier. Those figures describe the broader market setting; they do not isolate the effect of the September 1 operation.
Diplomatic channels have not formally closed. Earlier on September 1, Iranian President Masoud Pezeshkian said Iran would “immediately reciprocate” if the United States returned to commitments under an interim memorandum reached in June, according to Iranian state media cited by AP.
AP reported that the June arrangement called for an immediate ceasefire and a 60-day period of negotiations toward a wider agreement. It broke down soon afterward. No resumption of negotiations was confirmed before the cutoff.
Iran has also been discussing a framework with Oman for managing shipping traffic in the Strait of Hormuz, AP reported. Gulf governments have called for the strait to reopen without conditions. It was not clear whether Washington would accept an arrangement negotiated by Iran and Oman.
A separate issue concerns international oversight of Iran’s nuclear programme. AP reported that the International Atomic Energy Agency has been unable to inspect Iranian facilities affected by the 12-day war in June 2025. In a confidential report seen by AP, the agency said it could not provide information about the current size, composition or location of Iran’s enriched-uranium stockpile. The report does not establish that Iran has changed its nuclear activities; it records limits on inspectors’ access.
What Happens Next
CENTCOM may release a more detailed assessment of the September 1 operation, including target locations, weapons used and the military effects it says were achieved. Iranian authorities may also publish additional information about deaths, injuries and damage.
Jordan, Bahrain, Kuwait and the United Arab Emirates could issue further statements about reported missile and drone activity. Their accounts will be important in establishing the regional impact of Iran’s reported response.
Shipping operators and maritime-security authorities are likely to monitor tanker movements and new security warnings around the Strait of Hormuz. The United Kingdom Maritime Trade Operations centre may issue updates on the two reported tanker incidents.
Diplomatic attention will focus on whether Iran’s conditional offer to return to the June memorandum produces direct contact with Washington, and whether Iran’s shipping discussions with Oman gain support from neighbouring Gulf states or the United States.
The U.S. State Department renewed a regionwide Middle East travel alert on September 1, citing a complex security environment and the possibility of escalation.
How Signal Interpreted the Information
I compared contemporaneous statements from U.S. Central Command with reporting from The Associated Press and Al Jazeera. The official CENTCOM record received the greatest evidentiary weight for the timing of the U.S. operation and the target categories because it is the U.S. military’s direct public account.
The available sources consistently agree that U.S. strikes resumed on September 1, that the U.S. identified IRGC military targets, and that Iran reported retaliatory missile and drone operations. They also agree that the August 30 Larak Island exchange preceded the new escalation.
The evidence is less certain regarding casualty figures, damage to civilian sites, the details of alleged attempted Iranian attacks that CENTCOM cited, and responsibility for tanker incidents in or near the Strait of Hormuz. I could not independently verify Iran’s reported civilian-casualty toll or its claim of a drone operation against U.S. forces in Bahrain.
This article avoids drawing a conclusion about responsibility for individual civilian-harm allegations or about either side’s claims of control over the strait. The selection reflects public consequence rather than an ideological judgement: direct U.S.-Iran military action, regional missile activity and disruption to a major global energy route have international humanitarian, security and economic implications.
