Israel's siege of Gaza, which has stopped all food from entering the enclave, is being discussed in the International Court of Justice in The Hague over the measures contravening international humanitarian law.
Some 40 countries are set to speak during the five days of hearings that begin on Monday, which will begin with an address by representatives of the Palestinian Authority.
The blockade, which Israel began on 2 March, has cut off the entry of all supplies into the enclave, with food aid piling up on the border of the enclave.
The UN's World Food Programme has said that its stocks of food in the enclave have run out and that it is unable to provide for the two million people reliant on external aid.
Meanwhile, Israel's bombardment and military operations in the enclave continue, with strikes killing 17 people, including 10 in Beit Lahiya, according to health officials.
