The United States has launched a new wave of military strikes against Iran, targeting military infrastructure that Washington says has been used to threaten commercial shipping in the Strait of Hormuz, according to the U.S. Central Command (CENTCOM).

In a statement posted on Wednesday, CENTCOM said American forces began the operation at 6:00 a.m. Eastern Time, describing it as part of ongoing efforts to further degrade Iran's military capabilities.

"At 6 a.m. ET today, U.S. Central Command forces began launching a wave of strikes against Iran," CENTCOM said, adding that the operation was intended to reduce military capabilities used to attack commercial vessels transiting the Strait of Hormuz.

Later in the day, at approximately 7:30 a.m. ET, CENTCOM announced that U.S. forces had completed another round of precision strikes following a 90-minute operation.

According to the command, the latest strikes targeted coastal defense systems as well as cruise missile storage and launch sites on Greater Tunb Island, with the objective of further weakening Iran's ability to threaten international maritime traffic.

"CENTCOM conducted a morning round of strikes against Iran at 7:30 a.m. ET on July 15. CENTCOM launched precision munitions against coastal defense systems and cruise missile storage and launch sites on Greater Tunb Island during the 90-minute wave. The strikes further degraded Iran's ability to attack commercial shipping in the Strait of Hormuz," the statement said.

The latest military action follows an earlier seven-hour U.S. air and naval operation on Wednesday that reportedly targeted dozens of Iranian military sites.

The escalation comes amid growing concerns over security in the Strait of Hormuz, one of the world's most strategically important maritime chokepoints.

According to Bloomberg, International Maritime Organization Secretary-General Arsenio Dominguez said approximately 6,000 seafarers remain stranded in the Strait of Hormuz, warning that the waterway continues to pose an extremely high risk for commercial shipping. He said the organization supports international efforts aimed at ensuring the safety of crews operating in the region.

The renewed tensions follow the collapse of a memorandum of understanding previously reached between the United States and Iran. The agreement had facilitated the reopening of the Strait of Hormuz to commercial shipping. However, after U.S. President Donald Trump declared the agreement terminated, tensions escalated, culminating in Iran's renewed closure of the strategic waterway.
