In a statement released in New York at the noon briefing to correspondents, UN Secretary-General António Guterres reiterated his "total condemnation of the acts of terror committed by Hamas in Israel for which there can be no justification."

He said he would never forget the "horrendous images of civilians being killed and maimed and others being dragged away into captivity", calling again for their immediate release.

"The Secretary-General remains extremely distressed by the killing of civilians in Gaza and the humanitarian catastrophe that continues to unfold in Gaza, with an unimaginable toll on civilians", said Spokesperson Stéphane Dujarric.

He also reiterated his call for an immediate humanitarian ceasefire.

160 children killed daily

“Every day, you think it is the worst day and then the next day is worse,” UN health agency spokesperson Christian Lindmeier said, quoting a colleague in Gaza, which remains under almost complete blockade. “Access, access, access is necessary.”

The level of death and suffering is “hard to fathom”, Lindmeier told journalists in Geneva. On average, 160 children are killed every day in the enclave and the total death toll has passed 10,000, according to figures from the Ministry of Health in Gaza.

Meanwhile, in the Hamas-run enclave, Israeli bombardments have intensified and military operations on the ground are continuing against fighters linked to the 7 October attacks.

In Israel, people are “frightened, traumatized and anguished for their loved ones”, the UN World Health Organization (WHO’s) Lindmeier said, before reiterating wide-ranging calls on Hamas to release the hostages.

Many of those held captive need urgent medical attention, he stressed.

Diplomatic efforts

Echoing previous UN appeals, Lindmeier insisted that what is needed now is “the political will to at least grant a humanitarian pause and access to alleviate the suffering of the civilian population as well as the hostages in Gaza”.

Diplomatic efforts towards this objective have continued. UN rights chief Volker Türk began a five-day visit to the region in Cairo on Tuesday to engage with Government officials, civil society, victims and UN colleagues, stressing that “human rights violations are at the root of this escalation and human rights play a central role in finding a way out of this vortex of pain”.

He is set to visit Rafah on the Egypt-Gaza border before travelling to Jordan’s capital Amman.

UN humanitarian affairs coordination office (OCHA) spokesperson Jens Laerke confirmed to reporters in Geneva that the UN has been invited to the international conference on humanitarian aid for Gaza’s civilians hosted by the French Government in Paris on Thursday, and that it would be announced in due course who will take part on behalf of the Organisation.

‘Inhumane living conditions’

Meanwhile, the UN agency for Palestine refugees (UNRWA) said on Tuesday that over two in three Gazans have been displaced in one month.

“This comes with constant fear and inhumane living conditions for almost 1.5 million people”, UNRWA said, including daily struggles to find bread and water as well as regular telecommunications blackouts cutting people off from loved ones and from the rest of the world.

Over 717,000 people are sheltering in 149 UNRWA installations across the enclave, including in the north, which has been cut off from the rest of the Strip by Israeli military operations.

Hundreds of trucks waiting

“Nothing justifies the horror being endured by civilians in Gaza,” Mr. Lindmeier insisted, stressing their desperate need for water, fuel, food and safe access to health care to survive.

He reiterated the UN’s calls for “unhindered, safe and secure access” for some 500 trucks of aid a day, not only across the border but also “all the way through to the patients in the hospitals”, where surgeries including amputations were being performed without anaesthesia.

Hundreds of truckloads of aid are waiting for access at the Egypt-Gaza border and humanitarians on the ground in Gaza are on standby to facilitate the distribution of relief items, he said.

‘Real heroes’

Lindmeier also said that he was proud of the workers keeping the health system going in Gaza against all odds; “real heroes” who are “working under constant stress with no respite”.

WHO is mourning the 16 health workers who have been killed while on duty, he said, stressing that any attacks on health care are forbidden by international humanitarian law.

Overcrowding 'a major concern'

UN Spokesperson Stéphane Dujarric said the Egyptian Government has agreed to the deployment of a UN technical humanitarian team to provide advice to the Egyptian Red Crescent Society on the delivery of aid to Gaza, which will be based close to the Rafah crossing at Al Arish airport.

He said overcrowding in UN facilities in Gaza “remains a major concern”.

At the Khan Younis Training Center, where 22,000 displaced men, women and children have sought shelter, the space per person is less than two square metres, and there is one toilet for 600 people”, he said.

Our colleagues at UNRWA say that worsening sanitary conditions, along with the lack of privacy and space, pose great risks to the health and safety of people sheltering there.

Palestinian deaths on the West Bank

On the West Bank, 147 Palestinians have been killed, including 44 children, at the hands of Israeli forces. An additional eight Palestinians, including one child, have been killed by Israeli settlers.

“We also continue to see displacement in the West Bank with over 900 people displaced, since October 7th, amid settler violence or access restrictions”, added Dujarric.
