Today, Iran announced it would suspend cooperation with the UN's nuclear watchdog,

possibly preventing an independent review of the damage done to Iran's nuclear sites,

and the U.S. ended.

For 30 years, Nargis Mohamedi has fought for democracy and human rights, and in 2023 won the Nobel Peace Prize in absentia.

She's banned from travel and has been repeatedly arrested.

Most recently, she was held in Iran's notorious Avine prison and was released in December

on House Arrest, where she spoke with us today.

Israel's 12-day campaign against Iran facilitated by a massive intelligence penetration across society.

And now Iran says it's hunting for Israeli spies and their weapons of choice.

I witnessed Islamic Revolutionary Guard Corps forces in Tehran

stopping cars and dumping all the passengers' belongings into the street,

supposedly while searching for drones. It's an insult to the intelligence
