Israel will allow aid to enter Gaza from Egypt, prime minister Benjamin Netanyahu's office has said following demands by US president Joe Biden.
In a major breakthrough on Wednesday afternoon, Israel said while it will not allow humanitarian supplies into the besieged enclave viafrom the Israeli side of the border, it will not block aid coming from Egypt.
"In light of President (Joseph) Biden's demand, Israel will not thwart humanitarian supplies from Egypt as long as it is only food, water and medicine for the civilian population in the souther Gaza Strip," Mr Netanyahu's office said in a statement.
"Israel will not allow any humanitarian aid from its territory to the Gaza Strip as long as our hostages are not returned," it added.
It was not clear when the aid will start flowing. Egypt's Rafah crossing has only a limited capacity, and Egypt says it has been damaged by Israeli airstrikes.
It came after Mr Biden met with Mr Netanyahu in Tel Aviv earlier on Wednesday, when the US president said he asked tough questions, and discussed humanitarian needs.
The Gaza healthy ministry said on Wednesday 471 Palestinians were killed and more than 314 wounded in what it described as an "Israeli massacre" at the Al-Ahli al-Arabi Hospital in Gaza City on Tuesday.
US President Joe Biden claimed the blast was "done by the other team" during a press conference in Tel Aviv.
Israel said the blast was caused by a failed rocket launch by the Palestinian Islamic Jihad militant group, which denied blame.
Rishi Sunak has called for a "calm and cool” response to the incident, and said British intelligence services are examining evidence and "talking to allies to establish what’s happened".
