One Hundred and twenty people were injured while showing solidarity with Palestinians when Egyptian security forces dispersed them in Cairo.
The peaceful protest was staged by hundreds of pro-Palestine groups outside the Israeli embassy but soon clashes broke out when a group tried to force its entry into the building.
They were dispersed by the Egyptian security with tear gas and rubber-coated steel bullets.
At least 20 people were arrested.
In the West Bank, thousands of Palestinians took to the streets, waving flags in the Nakba protests against Israel.
President Mahmoud Abbas said the blood of Palestinians who died, will not go waste their blood [as] it was spilled for the freedom of our people and for their rights.
Abbas said the participation of such a large number of people in the protests was proof enough that the right is stronger than time, and the will of people is stronger than the power of the oppressive forces and the occupiers.
