The head of the United Nations children's agency UNICEF, has said that more than 420 children are being killed or injured in Gaza every day as Israel continues its sustained bombardment of the territory.
Catherine Russell was speaking at an emergency meeting of the UN Security Council. Neda Tofi is in New York.
Catherine Russell told diplomats the number of children dying should shake each of them to their core.
The head of the UN agency supporting Palestinians in Gaza Philip Lazar Renee said the human tragedy unfolding in the territory under their watch was unbearable.
3,200 children had been killed in Gaza in just 3 weeks, he said, surpassing the number of children killed annually across the world's conflict zones since 2019.
That he said could not be collateral damage.
The United States has said it is confident there will be an increase in humanitarian aid entering Gaza through the Rafah Crossing at the border with Egypt in the coming days.
The White House national security spokesperson John Kirby said there had been discussions with Israel about an imminent first phase of about 100 trucks a day.
He said Washington was doing everything it could to try to get aid to those who needed it in Gaza.
The United States is literally leading the effort to try to get humanitarian assistance into Gaza.
And if it wasn't, quite frankly, for American leadership, I don't think you'd see, in fact, I know you would see, the increase of the aid getting in.
Again, we know there's a lot more that needs to be done, but it's because of American leadership on the ground and American convening power that we're able to get that aid in and try to see if we can sustain it.
We're working very hard at this.
Mr. Kirby also said that while temporary humanitarian corridors should be explored, the US did not support a ceasefire as it would only benefit Hamas.
In the first known rescue of a hostage since Hamas seized more than 200 Israelis during its violent attack earlier this month, an abducted soldier has been reunited with her family.
Separately, Hamas has released a video filmed under duress, showing three women hostages held in Gaza.
One of them angrily criticizes the government of Benjamin Netanyahu. This report from Paul Adams.
Hamas know, only too well the anguish debate that is going on in Israel about how the government should go about securing the release of the hostages.
It knows that there are many many people who are deeply apprehensive about the government strategy, which is essentially to apply huge amount of military pressure in the belief that will end up yielding the hostages.
That is why this video was made.
And I think Mr. Netanyahu probably voiced the view of many when he called it a cruel psychological piece of propaganda.
