Gaza City: Ambulances were lined up at Malaka camp, east of Gaza City on Saturday as organisers prepared to mark a year of border protests.
The marches are planned to begin in the early afternoon.
Tension is growing after the death of Mohammed Saad, 21, early Saturday.
Gaza's Health Ministry said he was hit by Israeli army fire east of Gaza City near the perimeter fence.
The marches near the fence began a year ago, initially organized by grassroots activists.
Hamas quickly took the lead, but a steady large turnout was also driven by widespread despair in Gaza.
The border marches routinely ended in confrontations, with some of the Palestinian demonstrators burning tires, hurling fire bombs or setting off explosives and Israeli troops firing live rounds and tear gas.

According to a Gaza rights group and a count by The Associated Press, 196 Palestinians were killed in the demonstrations over the past year, including 41 minors, and thousands were wounded by live fire.
An Israeli soldier was also killed on the context of the marches.
Meanwhile a general strike called for by Hamas has paralyzed Gaza City to give workers and students time to participate in the protests.
