On the third day of US and Israeli attacks on Iran, the death toll has risen to at least 555 in Iran, with strikes occurring across 131 cities since Saturday, according to the Iranian Red Crescent Society. US President Donald Trump stated that large-scale military operations in Iran are ongoing and could last for weeks, with objectives including destroying Iran's missile capabilities and navy, and preventing nuclear weapons development, citing stalled diplomatic negotiations. US Defense Secretary Pete Hegseth indicated no immediate plans for ground troops but remained non-committal on future actions. Concurrently, Israeli strikes in Lebanon have killed at least 52 people, a response to Hezbollah rocket fire. The US has confirmed a fourth service member killed, while Iranian missile and drone attacks have targeted US allies across the Gulf, including Saudi Arabia's largest oil refinery. Kuwaiti air defenses mistakenly downed three US F-15 jets.
