Where Israel is launching a barrage of strikes on Lebanon late tonight as US officials try to track down how top secret intelligence about Israel's plan to hit back at Iran apparently leaked. Matt Bradley is in Beirut for us tonight. Matt, what are you seeing on the ground there?

Yeah, Halley. It's another loud and violent night here in Beirut. We've been watching these explosions lighting up the skyline behind me for hours. The Israelis are once again pounding Hezbollah targets throughout the country. But tonight, they have a specific target in the crosshairs, the Al-Qad Al-Hassan Foundation. Now, Israel's military accuses Iran of trying to finance Hezbollah's operations through these foundations.

Matt, what else do we know about this apparent secret document leak?

Three US officials told NBC News they're trying to figure out how these documents got out in the first place. Now, these are reports about Israeli plans to retaliate against that Iranian missile salvo earlier this month. They describe Israeli air exercises, rehearsing for a strike on Iran, and how Israel is moving its missiles around the country. Now, these documents, they don't really go into details about how or when the Israelis might attack Iran, but they do say that there's no indication that the Israelis are going to be using nuclear weapons. Halley.
