And Paranational Security Correspondent Greg Myrie is with us.

Hi, Scott.

And what can you tell us about this military operation?

Greg, did the president offer any details about the operation itself?

Before the strikes began, the president didn't say much about what his ultimate goal might be in Iran.

But that's changed today, hasn't it?

And Israel has tried to assassinate Iran's top leaders, according to a person briefed on the operation who spoke with NPR.

We're joined now from Tel Aviv by NPR's Daniel Estrin.

Daniel, thanks for being with us.

Give us a sense of what it's like right now where you are.
