Operation Dawn, code-name Fajr (الفجر) in Arabic,[1] was a rejected Egyptian military proposal planned by General Abdel Hakim Amer, as tension built between Israel and Egypt ahead of what was to become the Six Day War.
The Egyptian attack plan was to also involve strategic bombing of major ports, the Negev Nuclear Research Center near Dimona, airfields and cities.
Arab armies would then attack, effectively cutting Israel in half with an armoured thrust from northern Sinai via the Negev desert.
[1] According to the Israeli diplomat Michael Oren, Operation Dawn was called off after Nasser was informed by the Soviet Union that the United States was aware of the plan.
Israeli prime minister Levi Eshkol wrote on a copy of one of the urgent messages transmitted to the United States "All to create an alibi".
