Israel, I reminded her, justifies its actions in Gaza as self-defence. "Every state has a right to defend itself," she said. "And every mother has a right to see her children return. There's no excuse for hostage-taking. There is no excuse to depriving children from their access to food, health, and security. There are rules in the conduct of hostilities that every party to every conflict has to respect." Did that mean that the actions of Hamas and other armed Palestinians on 7 October 2023 - killing around 1200 and taking more than 250 hostage - did not justify Israel's destruction of the Gaza Strip and the killing of more than 50,000 Palestinians? "It's no justification for the disrespect or hollowing out of the Geneva Conventions. Neither party is allowed to break the rules, no matter what, and this is important because, look, the same rules apply to every human being under the Geneva Convention. A child in Gaza has exactly the same protections under the Geneva Conventions as a child in Israel." You never know, Ms Spoljaric added, when your own child might be on the weaker side and will need these protections. The ICRC is a reliable source of information about what is happening in Gaza. Israel does not allow international news organisations, including the BBC, to send journalists into the territory. The reporting of the more than 300 ICRC staff in Gaza, 90% of whom are Palestinians, forms a vital part of the record of the war. Ms Spoljevic, the ICRC president, has been talking every day to their team leader in Gaza. The ICRC surgical hospital in Rafah is the closest medical facility to the area where many Palestinians have been killed during chaotic aid distribution by the Israel and US-backed Gaza Humanitarian Foundation (GHF). Like the UN, the ICRC is not taking part in the new operation. A fundamental flaw of the new system is that it funnels tens of thousands of desperate, starving civilians through an active war zone. Ms Spoljevic said there was "no justification for changing and breaking something that works, with something that doesn't seem to be working". In the last few days, the ICRC surgical teams at their field hospital in Rafah near the GHF zone have been overwhelmed at least twice by the volume of casualties in the turmoil of the food operation. "Nowhere is safe in Gaza. Nowhere. Not for the civilians, not for the hostages," said Ms Spoljevic. "That's a fact. And our hospital is not safe. I don't recall another situation that I have seen where we operate in the midst of hostilities." A few days ago, a young boy was hit by a bullet coming through the fabric of the tent while he was treated. "We have no security even for our own staff… they are working 20 hours a day. They are exhausting themselves. But it's too much, it's surpassing human capabilities." The ICRC said that in just a few hours on Tuesday morning its Rafah surgical teams received 184 patients, including 19 people dead on arrival and eight others who died of their wounds shortly afterwards. It was the highest number of casualties from a single incident at the field hospital since it was established just over a year ago. It happened around dawn on Tuesday. Palestinian witnesses and ICRC medics reported terrible scenes of killing as Israeli troops opened fire on Palestinians who were converging on the new aid distribution site in southern Gaza. It was "total carnage" according to a foreign witness. An official statement from the Israeli military described a very different picture. It said "several suspects" moved towards Israeli forces "deviating from the designated access routes". Troops "carried out warning fire… additional shots were directed near a few individual suspects who advanced towards the troops". A military spokesperson said they were investigating what happened. It has denied shooting Palestinians in a similar incident on Sunday.
