The "Israeli" entity's military warned Gaza residents on Monday that it would stop any breach of its border fence and that those approaching it in a planned mass protest would be putting their lives in danger.
Tens of thousands are expected to head to the border Monday and the possibility of large crowds breaking through the fence has been raised.
Monday's march is part of a weeks-long campaign to break the decade-old border blockade of the territory by Israel and Egypt.
Since weekly border marches began in late March, 42 Palestinian protesters had been martyred and more than 1,800 wounded by "Israeli" army fire.
Leaflets dropped over Gaza by army jets warned that those approaching the border "jeopardize" their lives. The warning said the army is "prepared to face all scenarios and will act against every attempt to damage the security fence..."
Monday's protest also targets the inauguration of a US Embassy in contested al-Quds [Jerusalem] later that day.
US President Donald Trump announced his decision in December to recognize al-Quds as the "Israel" entity's so-called capital, triggering a joyous reaction from "Israeli" Prime Minister Benjamin Netanyahu's government. The move infuriated the Palestinians.
Netanyahu praised Trump's "bold decision" in upending decades of US policy by recognizing al-Quds as the entity's so-called capital. "It's the right thing to do," a smiling Netanyahu told the jubilant crowd at a reception in al-Quds late Sunday.
Although Trump has said his declaration does not set the final borders of the city, his recognition of al-Quds as the entity's so-called capital has been perceived by both the entity and the Palestinians as taking "Israel's" side in the most sensitive issue in their conflict. Only two countries, Guatemala and Paraguay, have said they will follow suit. Most of the world maintains embassies in Tel Aviv, saying the al-Quds issue must first be resolved.
In a reflection of the deep sensitivities, dozens of countries - including Britain, France and Germany - skipped a celebration Sunday night at the "Israeli" Foreign Ministry.
Monday's opening will be attended by Trump's daughter Ivanka and son-in-law Jared Kushner, who both serve as White House advisers. Kushner leads the Trump Mideast team.
