One of the key agencies overseeing the provision of aid into Gaza is the UN Office for the Coordination of Humanitarian Affairs.

Earlier today, I spoke with its leader, Tom Fletcher, who was in Gaza earlier today and joined us from Jerusalem.

You were in Gaza earlier today. What did you witness, especially in the areas that were harder to reach due to the fighting?

Well, thanks. I mean, I came in through the north, which is the area worst affected by the conflict of the last 14, 15 months.

And it's desolate, and it's been pummeled. You can't tell what was a house, what was a school,

what was a hospital. And you see civilians picking through the wreckage, returning to their homes.

And it takes them time to even find where their homes were because everything has been flattened.

So it's grim, it's desolate.

But they are heading home and they are trying to rebuild.

Parts of northern Gaza were on the brink of famine.

What's the situation now?

They were.

So two and a half weeks ago when we got the ceasefire in place,

we were very, very worried about starvation levels and famine.

We've now got two and a half weeks of trucks, convoys,

almost 14,000 trucks have gone in in that time.

So we've made progress in getting food to those who need it, to the survivors.

And the risk is receding of famine.

We've got food to a million people.

But the needs are still massive.

I'd say the biggest needs right now are tents, shelter,

because a lot of people are trying to head back to where their homes were and winter is here.
