The United States and Iran have sharply escalated their military confrontation, exchanging fresh attacks for a seventh consecutive night after a fragile ceasefire collapsed.

The latest strikes have expanded the conflict across the Gulf, threatened critical infrastructure, and intensified concerns over global oil supplies through the Strait of Hormuz.

The US military said it completed another wave of attacks on Iran late Friday under the direction of President Donald Trump, marking the seventh straight night of American operations.

According to the US Central Command (CENTCOM), the strikes targeted surveillance sites, military logistics infrastructure, underground weapons storage facilities and maritime capabilities. The military said fighter aircraft, aerial drones, warships and other military assets were used during the operation.

CENTCOM added that more than 50,000 US service members remain deployed across the Middle East and are “vigilant, lethal, and ready.”

The US military also confirmed that its latest campaign included strikes on military logistics infrastructure, marking the first time in more than a week that it publicly acknowledged targeting infrastructure-related sites.

Iranian civilian infrastructure suffers damage

Iranian media reported that explosions rocked multiple cities, including Yazd, Ahvaz, Lar, Bandar Abbas, Sirik, Qeshm Island, Omidiya, Jask and Khorramabad, as US attacks continued overnight.

In Hormozgan province, Iranian state television said three people were killed and eight others were injured after strikes damaged bridges, a road tunnel and other transport routes. Authorities later closed several roads across the province.

Iranian officials also reported that electricity facilities and desalination pumps in Jask County were struck, cutting drinking water supplies to several villages.

A deputy governor in Hormozgan said US rockets hit desalination pumps at Bunji village’s dock, while local authorities said damage assessments and restoration work were underway.

Separately, Iran’s semi-official Tasnim news agency reported that US strikes heavily damaged two bridges along the Bandar Abbas-Rudan highway, killing several civilians and injuring others.

Earlier on Friday, Iranian state media said at least five bridges were struck in southern Iran. Seven people were reported killed in Bandar Khamir, where the train station was also hit. An airport in Iranshahr, near Pakistan’s border, was also reportedly targeted.

According to Iran’s Ministry of Health, the overall death toll from U.S. attacks had reached 38 by the morning of July 16, while more than 400 people had been injured.
