Targets in at least nine different towns and cities were struck across Iran overnight, according to local officials, Iranian state media and verified videos.

Several more locations were reported to have been hit. Several explosions were reported on the island of Abu Musa at the entrance of the Strait of Hormuz in the Persian Gulf. The island has a small airport and town.

Explosions were also reported in the port cities of Bushehr, Bandar Abbas, Jask, Sirik and the military facilities around Konarak near Chabahar.

In Sirik, a local official said three people were killed and 15 injured after a strike on a commercial fishing pier.

Eight missiles launched by Iran toward Jordanian airspace were intercepted on Thursday, according to a statement from the Jordanian Armed Forces.

No damage or causalities have been reported, according to the armed forces. Air raid sirens could be heard in parts of Jordan including in Amman.

The U.S. Embassy in Jordan issued a security alert on Thursday, warning of potential "missiles, drones, or rockets" entering Jordanian airspace.

"Seek overhead cover and shelter in place immediately," the alert said. "Remain indoors and pay attention to local announcements and alerts."

At least one person was injured in Kuwait as the country's air defences shot down drones and missiles on Thursday morning, the country's army said.

At least three ballistic missiles, one cruise missile and 10 drones were "successfully intercepted and dealt with," according to a statement posted by the Kuwait Army.

"This resulted in material damage due to the fall of debris in several locations across the country, in addition to one human injury, where the injured person is receiving the necessary medical care, and their condition is stable," the army said.

U.S. forces have completed an additional round of strikes against Iran, striking roughly 90 military targets, U.S. Central Command said in an update late Wednesday.

CENTCOM said the targets included air defense systems, coastal surveillance assets, missile and drone storage sites, naval capabilities and military logistics infrastructure along Iran’s coastline.

The strikes "further degrade Iran's ability to attack commercial shipping and innocent civilian mariners in the Strait of Hormuz."

The night before, CENTCOM said U.S. forces hit approximately 80 Iranian military targets.
