US Central Command said the strikes targeted key Iranian military capabilities. According to a US official, the operation focused on coastal surveillance systems, as well as Iran's drone and missile infrastructure.

Speaking at the White House, President Donald Trump warned that the US would intensify its military campaign against Iran, saying the strikes would continue over the coming days.

Trump said the United States would take control of the strategically important Strait of Hormuz, accusing Iran of violating a military agreement and continuing drone activity in the region.

Trump said recent US strikes had severely damaged Iran's military capabilities, including anti-aircraft systems, and warned of further action if Iran continued drone operations.

Trump claimed that Washington and Tehran had reached a completed agreement after lengthy negotiations, but alleged that Iran later sought changes, leading to the collapse of the deal.

The US president said Iranian negotiators initially agreed to the terms after an 11-hour meeting but later requested revisions, which the US rejected.
