U.S. forces launched a new round of strikes against Iran on Monday, U.S. Central Command (CENTCOM) said.
The strikes began at 4 p.m. EDT, or 2000 GMT, and were "designed to further degrade Iranian military capabilities used to attack commercial shipping in the Strait of Hormuz," CENTCOM said.
The statement came as the United States continued to carry out airstrikes against Iran, with the attacks largely focused on southern Iran.
Tehran has retaliated with strikes targeting facilities and bases in several regional countries that it says are used by the U.S. military.
The latest exchange of fire between the two countries comes despite a Pakistani-brokered framework agreement signed in June to end the war and reach a lasting peace deal.
Air defense systems were heard operating near the Bushehr Nuclear Power Plant in southern Iran, according to the semi-official Mehr News Agency.
No further details were immediately available.
U.S. President Donald Trump said Monday that Iran would pay "many times over" for any American troops killed amid ongoing hostilities in the Middle East.
"Every time Iran kills an American Soldier they will pay for that killing many times over," Trump wrote on Truth Social.
He said the directive had been passed on to Defense Secretary Pete Hegseth, Joint Chiefs of Staff Chairman Daniel Caine and "every Leader in the Military."
The Pentagon confirmed three U.S. deaths over the weekend, including two at a military base in Jordan and one in northern Iraq.
The United States and Iran have considered a 10-day ceasefire to halt hostilities and encourage a return to negotiations, CNN reported.
The proposed pause in fighting would also include lifting restrictions on the Strait of Hormuz, according to the report.
The White House said diplomacy was continuing alongside efforts to make Iran "pay" for the recent deaths of U.S. soldiers.
"Right now, President Trump is focused on making Iran pay for their violations of the MOU and their continued acts of terrorism in the Strait of Hormuz," a U.S. official said, referring to the memorandum of understanding.
"In addition, the president will make Iran pay for the recent deaths of U.S. soldiers," the official said. "These devastating blows will continue until the president deems otherwise, but talks between our countries are continuing."
