Sixty-four public figures, including seven Nobel Peace Prize winners, have called for an international arms embargo on Israel for its “war crimes and possible crimes against humanity” in Gaza. The statement came in a letter published in Britain’s The Guardian on Friday.

“Israel has once again unleashed the full force of its military against the captive Palestinian population, particularly in the besieged Gaza Strip, in an inhumane and illegal act of military aggression. Israel’s ability to launch such devastating attacks with impunity largely stems from the vast international military cooperation and trade that it maintains with complicit governments across the world,” read the statement.

“We call on the UN and governments across the world to take immediate steps to implement a comprehensive and legally binding military embargo on Israel, similar to that imposed on South Africa during apartheid,” the letter concluded.

Among the signators were Nobel peace laureates Desmond Tutu, Betty Williams, Federico Mayor Zaragoza, Jody Williams, Adolfo Peres Esquivel, Mairead Maguire and Rigoberto Menchu.

Also signing were academics Noam Chomsky and Rashid Khalidi, filmmakers Mike Leigh and Ken Loach, musicians Roger Waters and Brian Eno, writers Alice Walker and Caryl Churchill, and journalists John Pilger and Chris Hedges. Two Israelis, academics Ilan Pappe and Nurit Peled, signed the letter as well.
