Israel has declassified more than 30 secret orders made by government and military leaders, which it says rebut the charge that it committed genocide in Gaza, and instead show Israeli efforts to diminish deaths among Palestinian civilians.

The release of the documents, copies of which were reviewed by The New York Times, follows a petition to the International Court of Justice by South Africa, which has accused Israel of genocide. Much of South Africa’s case hinges on inflammatory public statements made by Israeli leaders that it says are proof of intent to commit genocide.

Part of Israel’s defense is to prove that whatever politicians may have said in public was overruled by executive decisions and official orders from Israel’s war cabinet and its military’s high command.

The court, the U.N.’s highest judicial body, began hearing arguments in the case this month, and is expected to provide an initial response to South Africa’s petition — in which it could call for a provisional cease-fire — as soon as Friday.
