The Palestinian Health Ministry said the fatalities were caused on Sunday, naming two of the slain Palestinians as Hussein al-Amour, 25, and Abdul Haleem al-Naqa, 28.
The ministry said the attack targeted an observation post belonging to the Palestinian resistance group, the Islamic Jihad. Israel's military alleged that the shelling was retaliation for an explosive device near Gaza’s fence, Press TV reported.
The military on Saturday announced the death of a soldier who was injured during a raid in the occupied West Bank on Thursday when Palestinians reportedly dropped a stone slab on his head from a building.
Israeli warplanes on Saturday hit what the regime called targets belonging to the Hamas resistance movement, without any report of casualties.
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 largest number of fatalities on a single day came on May 14, which coincided with the 70th anniversary of Israel’s creation in 1948.
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 Jerusalem al-Quds.
