Accused of committing genocide against Palestinians, Israel insisted at the United Nations’ highest court Friday that its war in Gaza was a legitimate defense of its people and that it was Hamas militants who were guilty of genocide.

Israel described the allegations leveled by South Africa as hypocritical and said one of the biggest cases ever to come before an international court reflected a world turned upside down. Israeli leaders defend their air and ground offensive in Gaza as a legitimate response to Hamas’ Oct. 7 attack, when militants stormed through Israeli communities, killing some 1,200 people and taking around 250 hostage.

Israeli legal advisor Tal Becker told a packed auditorium at the ornate Palace of Peace in The Hague that the country is fighting a “war it did not start and did not want.”

“In these circumstances, there can hardly be a charge more false and more malevolent than the allegation against Israel of genocide,” he added, noting that the horrible suffering of civilians in war was not enough to level that charge.

South African lawyers asked the court Thursday to order an immediate halt to Israeli military operations in the besieged coastal territory that is home to 2.3 million Palestinians. A decision on that request will probably take weeks, and the full case is likely to last years — and it’s unclear if Israel would follow any court orders.

On Friday, Israel focused on the brutality of the Oct. 7 attacks, presenting chilling video and audio to a hushed audience.

“They tortured children in front of parents and parents in front of children, burned people, including infants alive, and systematically raped and mutilated scores of women, men and children,” Becker said.
