We'll hear about that from our correspondent in Jerusalem in just a moment.

But first to Lebanon itself and Dr Ahmad Zraik, an emergency care doctor in Nabatea Government Hospital.

Last night it was like a disaster.

The BBC's Karim Torbay in southern Lebanon told us more about how the Israeli attacks are affecting people there.

But this morning, everything changed completely.

And there has been a number of strikes without any warning.

Israel pounded the area, the sector of Naboti in south Lebanon.

And this triggered another wave of displacement from people who just came back to check on their houses.

Of course, what they saw is massive destruction all over.

Lots of houses, shops, cars, everything is completely destroyed.

But some people were still wanting to come back.

And today they had to once more pack their stuff and leave.

And do we know what triggered this particular escalation?

Obviously, Hezbollah and Israel are not parties to the US-Iran deal and both have been trading attacks for months and even years.

They are not direct parties to this deal.

But the way this deal worked is basically that the United States said it will put pressure on Israel to convince Israel to stop its attacks on Lebanon.

And Iran, which is seen as the main sponsor of Hezbollah, would ask Hezbollah to commit to the ceasefire and to stop attacking Israel as well.

And that was the understanding that both parties—Iran is a very important regional power—

America was all its clout, can force the parties on the ground to stop, even if this is happening in a third country.

But this didn't actually materialize.
