The UN warns that the humanitarian crisis in Gaza is growing more acute.

In southern Gaza, a quarter of the population faces catastrophic levels of food insecurity.

In northern Gaza, nearly one in three children are

severely malnourished. Nick Schifrin speaks to the UN's top humanitarian

official about Gaza, Sudan, and what he calls one of the worst years for humanitarian crises.

The UN says every single one of Gaza's 2.2 million or so residents need food assistance

and the threat of famine is looming.

One of the leading officials dealing with this crisis is the UN's under-secretary

General for Humanitarian Affairs and Emergency Relief Coordinator Martin Griffiths who will be stepping down soon after a 50 year

career on humanitarian and conflict work.

Martin Griffith, thanks so much.

Welcome back to the news hour.

The executive director of the World Food Program,

Cindy McCain, recently said that Northern Gaza is in quote,

full-blown famine. Do you agree?

I would agree with their in substance in the sense that there is a very very as you know

stringent technical process independent of the UN by the way to identify when famine exists, but we know from Gaza, we know from elsewhere that don't

wait for the declaration, of the official declaration, to know that people are dying of hunger, kids are dying of malnutrition.

Today the US military announced that a floating pier designed to deliver humanitarian aid to Gaza has been attached to Gaza.

They have hundreds of tons of aids ready for delivery, thousands more tons in the pipeline.

How much of an impact could this kind of thing have?

It's very helpful. We've always said that any way to get more aid in should be welcomed.
