Mirjana Spoljaric says Palestinians have been stripped of human dignity.
Gaza has become worse than hell on Earth, the president of the International Committee of the Red Cross tells the BBC's Jeremy Bowen.
Mirjana Spoljaric says Palestinians have been stripped of human dignity and international humanitarian law is being hollowed out.
It comes as aid distribution centres in Gaza are closed today, as Israel's military warns roads leading to the sites will be considered "combat zones".
At least 27 Palestinians were killed by Israeli fire close to an aid point on Tuesday, Hamas-backed local officials said - the third deadly incident this week near a site run by the Gaza Humanitarian Foundation (GHF).
The IDF said its troops fired shots after identifying what it described as suspects who moved towards them "deviating from the designated access routes".
Elsewhere, 12 Palestinians have been killed after an Israeli strike hit a school housing displaced people in Khan Younis, the Hamas-run Civil Defence agency and a hospital official say.
Israel does not allow international news organisations, including the BBC, into Gaza, making verifying what is happening in the territory difficult.
Starmer say Israel's recent action is 'intolerable' and 'appalling'
Meanwhile in London, Prime Minister Keir Starmer responds to a question about Gaza in the House of Commons.
He says: "We have strongly opposed the expansion of military operations and settler violence, and the blocking of humanitarian aid."
He adds that further actions against Israel will be considered, including sanctions.
Starmer continues: "We need to get back to a ceasefire. We need the hostages who've been held for a very long time to be released and we desperately need more aid at speed and at volume into Gaza, because it's an appalling and intolerable situation."
