U.S. forces launched a concentrated series of overnight strikes across southern Iran, targeting bridges, railway links and coastal facilities as Washington expanded its continuing military campaign against Tehran.

A senior U.S. official told The Wall Street Journal that the attacks were designed to disrupt supply routes leading to Bandar Abbas, a strategically important port city that hosts a major naval base used by Iran’s Islamic Revolutionary Guard Corps.

The base serves as a central hub for Iranian operations around the Strait of Hormuz, one of the world’s most important energy shipping routes.

The latest targets suggest that the U.S. campaign is increasingly focusing on Iran’s military logistics network as well as its missile, air-defense and maritime capabilities.

Bridges and railway connections hit

Iranian state television reported that at least five bridges were struck across the southern province of Hormozgan. The attacks forced authorities to close several roads connecting Bandar Abbas with neighboring provinces.

Among the reported targets was a highway bridge linking Bandar Abbas with Shiraz near the city of Bandar Khamir. Iranian media also reported damage to the Gharifeh and Kahurestan bridges and disruptions to electricity supplies in surrounding areas.

A railway connection near Bandar Khamir was also reportedly hit, potentially affecting the movement of personnel and equipment between Iran’s central provinces and forces stationed along the southern coast.

Iranian state media said seven people were killed and nine others wounded in strikes on two bridges near Bandar Khamir. Separate reports claimed that a residential area in Bandar Abbas had been hit, killing one person and injuring eight.

The casualty figures and circumstances could not be independently verified. Reuters reported that it was unable to confirm some accounts of civilian casualties released by Iranian media.

Despite the damage, other roads leading toward Bandar Abbas reportedly remained open. U.S. officials have not announced plans for a ground operation in Hormozgan, although the focus on transport infrastructure has fueled speculation that Washington is attempting to isolate Iranian forces operating along the coast.

Chabahar port facility damaged

The strikes extended eastward to the port of Chabahar on the Gulf of Oman, where Iranian media reported the collapse of a control tower overlooking commercial operations.

U.S. Defense Secretary Pete Hegseth subsequently shared an image appearing to show the damaged tower.

Chabahar is an important regional trade center and provides Afghanistan with a route to international markets that does not pass through Pakistan. India has also supported the port’s development as part of efforts to strengthen its commercial links with Afghanistan and Central Asia.

Additional explosions were reported near Qeshm Island, Sirik, Bushehr and Bandar Abbas. Iranian media also reported attacks near Iran Shahr Airport and around Ahvaz in southwestern Iran, although comprehensive assessments of the damage were not immediately available.

CENTCOM confirms expanded campaign

The U.S. Central Command said it had completed another major wave of attacks, marking the sixth consecutive night of American strikes.

According to CENTCOM, fighter aircraft, drones and warships struck dozens of military targets, including coastal surveillance positions, air-defense systems, logistics infrastructure and Iranian maritime capabilities.

The United States has also intensified enforcement of its maritime blockade. American forces said they redirected three commercial vessels, disabled another vessel that refused to comply with instructions and boarded a tanker as part of inspection operations.

The latest campaign follows previous attacks against an Iranian facility used to support submarines and unmanned maritime vessels.

President Donald Trump has said that U.S. operations will continue and could be expanded to additional energy and transportation facilities. The White House, meanwhile, maintains that Tehran has continued to express interest in negotiations despite the escalating attacks.

Iran launches retaliatory strikes

Iran responded by announcing attacks against U.S. military support facilities and deployment sites in Kuwait. Tehran also claimed that it had struck a U.S. special operations position near Al-Tanf in Syria, damaging a radar system and destroying military helicopters.

Those claims were not independently verified. A Syrian military source told Reuters that the attack near Al-Tanf caused no casualties or significant damage.

Iranian officials warned that infrastructure throughout the Middle East could be targeted if the United States broadens its campaign against Iranian facilities.

Explosions were reported over Doha early Friday as Qatar’s air defenses intercepted incoming Iranian missiles. Qatari authorities issued emergency warnings instructing residents to seek shelter and said a child was injured by falling debris.

Iran also launched attacks toward Bahrain and Kuwait, while Jordan’s military reported intercepting three Iranian missiles. Air-defense activity and explosions were additionally reported over parts of Iraq’s Kurdistan region.

The renewed fighting follows the collapse of a temporary ceasefire reached the previous month. Shipping through the Strait of Hormuz has since been severely disrupted, contributing to higher oil prices and renewed concerns about the security of international energy supplies.

With both sides expanding their target lists, the conflict is moving beyond direct attacks on military positions and placing growing pressure on the transport, maritime and economic infrastructure supporting operations throughout the region.
