Israel's military said today it's preparing for a ground invasion of Lebanon.

U.S. officials are frantically trying to avoid all-out war between Israel and Hezbollah

after more than a week of unprecedented Israeli attacks on the militant group

which have killed hundreds and injured thousands more.

Nick Schifrin is here now with the detail so Nick how tense is the situation

along the border right now?

It's extremely tense, Jeff.

This has been the deadliest week in Lebanon for decades,

and that violence continued today.

Israel said that it struck some 350 Hezbollah sites including some associated with the Intelligence

Directorate to quote make it more difficult for Hezbollah to produce an intelligence

assessment.

Lebanese authorities say the strikes killed 50 on top of the more

than 550 killed the previous two day but meanwhile has blah continued its own

strikes into Israel including its hit villages near the border, wounding at least two civilians.

Hezbollah also launched its first ballistic missile at Tel Aviv.

It was intercepted by Israeli air defense.

But as you said, Jeff, Israel went further today than it has in the

past calling up two reserve brigades to deploy them to the northern area along the

Lebanese border. And the IDF's chiefs of staff, Hurti Hallavi,

warned today that troops needed to prepare for, quote, possible entry into Lebanon.

We are preparing the process. Lebanon.
