US Secretary of War Pete Hegseth posted a picture on platform "X" showing what appears to be the collapse of an Iranian tower, while official Iranian media said that US forces launched an attack targeting a maritime observation tower in the Iranian city of Chabahar for the third time this week.

The official Iranian news agency Fars and the Islamic Republic of Iran Broadcasting said that the attack was a missile strike targeting the tower, which is mainly used in search and rescue operations involving fishermen at sea, in addition to ensuring maritime security.

Hegseth posted a picture on platform "X" showing what appears to be the collapse of the tower, in response to a previous post that said: "Iran does not control the Strait of Hormuz."

Earlier on Friday, CNN obtained a video and geolocated it, showing a drone flying over a populated area in Chabahar while smoke rises on the horizon.

Chabahar, located on the northern shores of the Gulf of Oman, was attacked earlier in the war, but it has become a major target since the ceasefire collapsed.

US attack on Iranian military sites

The US Central Command earlier announced in a statement that "US forces, including fighter jets, drones, and warships, launched precision munitions targeting dozens of Iranian military sites, such as coastal surveillance and air defense sites, military logistics infrastructure, and naval capabilities."

On Thursday evening, US shells targeted Qeshm Island and the vicinity of Bandar Abbas—which hosts Iran's largest port and key facilities of the navy and the Revolutionary Guard—both located on the Strait of Hormuz.

Iranian media also reported US strikes late Thursday evening on 3 bridges and a train station in the coastal city of Bandar Khamir, and a US missile attack on Iranshahr Airport in southeastern Iran.

Tehran launched missiles and drones targeting US military bases in neighboring countries, including an air base recently expanded in Jordan, which Iran said was used in a US attack on an Iranian children's cancer hospital on Wednesday night.

Decline in navigation in the Strait of Hormuz

US President Donald Trump has repeated his threats in recent days to target Iranian power plants and bridges in an attempt to force Iran to ease its control over the strait, through which about a fifth of peacetime oil and natural gas trade passed. The US has also reimposed a naval blockade on Iranian ports to halt crude oil shipments.

Weekly cargo shipments through the strait fell by about a quarter at the beginning of the month, according to Lloyd's List Intelligence, a specialized maritime data firm, and that was before the recent escalation of mutual attacks.

Due to the risks, some oil tankers are crossing the strait with their positioning systems turned off, while many remain at their positions, according to Lloyd's on Thursday.

In a post on platform "X", US Central Command said its forces redirected 3 commercial vessels that attempted to breach the blockade, disabled a ship that did not comply, and boarded another "to ensure full compliance."
