On Day 2 of the U.S.-Israel war on Iran, the Pentagon confirmed the first American casualties, with three U.S. service members killed in Kuwait.

President Donald Trump said the operation will continue “until all objectives are achieved” and could last up to four weeks, with more casualties possible.

The initial strikes killed Ayatollah Ali Khamenei and about 40 senior Iranian officials, based on intelligence shared by the CIA with Israel.

Benjamin Netanyahu stated that Israel’s attacks on Iran will intensify in the coming days, CBS News has reported.

The campaign is being coordinated using months of intelligence to target key Iranian leadership and military infrastructure.
