U.S. and Iran Trade New Missile Strikes as Gulf Risks Rise

The United States and Iran exchanged new missile barrages on Thursday, July 30, after several days of reduced fighting, renewing concern that the five-month conflict could spread across the Gulf and disrupt commercial shipping.

Jordan said it intercepted Iranian missiles for the second consecutive day, while Kuwait reported that a strike in the northern part of the country killed one worker at a building used by a Chinese company. Jordan and Kuwait both host U.S. troops, according to Associated Press reporting.

What happened on July 30

The latest exchange followed what the U.S. military described as a “heavy wave of strikes against Iran.” U.S. Central Command said American forces struck dozens of targets linked to Iran’s Revolutionary Guard, including military command centers, missile and drone facilities, and coastal surveillance and defense sites.

Those details represent the U.S. military’s account of its operations, not an independent assessment of battlefield damage. In its 2026 posture statement, Central Command said its regional priorities include deterring Iran and allied armed groups, protecting U.S. forces and partners, and maintaining maritime security.

Iran’s official IRNA news agency reported that three people were killed and two were wounded in a strike on Qeshm Island, near the Strait of Hormuz. The casualty report was not independently confirmed in the approved reporting.

The Iraq escalation came first

The renewed U.S.-Iran missile exchange came one day after the United States partnered with Saudi Arabia in strikes against Iran-backed militias in Iraq on Wednesday, July 29. The Associated Press reported that at least 20 militia fighters and six Iranian advisers were killed. The figures were not independently verified in the approved sources.

Saudi Arabia had accused Iraqi militias of attacking its oil facilities. An umbrella group of Iraqi militias initially denied those allegations, while Houthi forces in Yemen separately claimed attacks on Saudi energy infrastructure. Saudi participation in the July 29 strikes adds another regional government and more critical infrastructure to an already widening security picture.

Why the Strait of Hormuz matters

The conflict is also affecting the movement of energy and commercial cargo. Shipping traffic through the Strait of Hormuz fell from 82 ships during July 13-19 to 39 ships during July 20-26, according to Lloyd’s List Intelligence data cited by the Associated Press.

The waterway connects the Persian Gulf with the Gulf of Oman and the wider Indian Ocean. It is a major route for oil, liquefied natural gas and other commercial shipments. A decline in traffic does not mean the strait has been closed, but it can increase delays, insurance costs and pressure on alternative routes before any complete shutdown occurs.

The United Nations warned on July 24 against further escalation in the U.S.-Iran war and highlighted risks to civilians and global shipping as fighting affected the Strait of Hormuz and the Red Sea. That warning remains relevant as attacks reach neighboring countries and commercial routes.

What remains unconfirmed

Fires were also reported Wednesday on two natural-gas vessels at Egypt’s Damietta port after drone strikes, according to the British maritime security firm Ambrey and Egyptian officials. Egypt said an initial investigation found that a drone caused the fires and that investigators were examining where it came from.

Responsibility remained unresolved. The Houthis denied involvement, and the approved reporting does not establish that Iran or an Iranian-backed group caused the fires. No injuries were reported.

What to watch next

The immediate indicators of further escalation are additional attacks on Gulf infrastructure, more military activity around Hormuz, and continued strikes by Iran-linked armed groups. For shipping operators and energy markets, the key practical signal will be whether vessel traffic begins to recover or falls further.

The central question is whether the recent pause in fighting will hold. Diplomatic claims will need to be measured against concrete evidence: a sustained reduction in missile and drone attacks, restored commercial traffic through Hormuz, and formal negotiations that produce verifiable commitments. For now, the July 30 exchanges show that the pause did not amount to a restored ceasefire.
