An Israeli tank on Sunday fired a shell in southern Gaza, where civilians live.
Zionist regime claimed the attack came in response to the finding of an explosive device at the border fence between Gaza and the occupied land.
The fatalities have been caused by the Israeli fire since March 30, when people in the besieged coastal territory began peaceful rallies near the fence demanding the right to return to their homeland.
The Palestinians were peacefully commemorating the Nakba (Catastrophe) Day, while also protesting the US relocation of its embassy from Tel Aviv to the holy occupied city of al-Quds.
