Iran's supreme leader's presumed death is "day of celebration," Masih Alinejad s

Iranian-American activist and CBS News contributor Masih Alinejad said Iranians are experiencing a range of emotions, including hope and concern, after U.S. and Israel launched a major operation against Iran. She added Iranians are concerned the attack won't lead to regime change, which she says is a "huge risk for people inside Iran." She also reacted to New York City Mayor Zohran Mamdani's statement on the military operation and reports that Iranian Supreme Leader Ayatollah Ali Khamenei is presumed dead after the strikes.CBS News 24/7 is the premier anchored streaming news service from CBS News and Stations that is available free to everyone with access to the internet and is the destination for breaking news, live events, original reporting and storytelling, and programs from CBS News and Stations' top anchors and correspondents working locally, nationally and around the globe.
