Russia has issued a strong warning to the United States, calling threats of military action against Iran "categorically unacceptable" and warning of "disastrous consequences" for regional and global security. Moscow accused the US of "subversive external interference" and cautioned against using Iran's internal unrest as a pretext for aggression. Meanwhile, US President Donald Trump publicly supported Iranian protesters, urging them to continue and stating "Help Is On Its Way," amid reports of significant casualties during a government crackdown.
