Judge Nawaf Salam, head of the International Court of Justice, says Israel must immediately hold its military offensive.
The court was ruling on South Africa's emergency request to order a halt to the Israeli military offensive in Gaza, with Pretoria accusing Israel of "genocide".
"Israel must immediately hold its military offensive of any other action in the Rafah governorate which may inflict on the Palestinian group in Gaza conditions of life that could bring about its physical destruction in whole or in part."
