DUBAI, United Arab Emirates—Explosions sent up clouds of dark smoke in the Iranian capital city early Saturday, and Tehran retaliated by firing missiles at Israel as the United States warned of a forthcoming bombing campaign that officials said would be the most intense yet in the weeklong conflict.
There was no foreseeable end to the fighting. U.S. President Donald Trump’s administration approved a new $151 million arms sale to Israel after Trump said he would not negotiate with Iran without its “unconditional surrender.” Iran’s U.N. ambassador said the country would “take all necessary measures” to defend itself.
