WASHINGTON - Some 40 Iranian officials were killed in the US-Israeli attack on Saturday, CBS News reported, citing anonymous sources.

Fox News, citing Israeli officials, also said that Saturday's strikes killed more than 40 senior Iranian security and government figures, noting that five to 10 top Iranian leaders were killed, along with Supreme Leader Ayatollah Ali Khamenei, who were meeting at a compound in Tehran.

Earlier Saturday, when announcing Khamenei's death, US President Donald Trump said the massive military campaign against Iran will continue.

"The heavy and pinpoint bombing, however, will continue, uninterrupted throughout the week or, as long as necessary," Trump said in a post on social media.
