According to the statement, the fact that the protesters were killed while standing between 300 and 600 meters from the border "proves that snipers deliberately targeted protesters."
The Gaza Health Ministry said on Friday that four protesters were killed by Israeli forces.
"What happened on Friday is nothing but a crime and crossed the red lines," the statement added, "and when it comes to Palestinian blood – money, electricity or water will not deter the factions from doing what they are tasked with."
The "enemy's" actions on the ground next Friday will determine whether the Palestinians will deliver a "harsh response."

On Saturday, Palestinian President Mahmoud Abbas accused Israel of transferring funds to Hamas and Gaza, resulting in violent terror attacks orchestrated by the group and targeting the West Bank.
Speaking in the beginning of a meeting of the Palestinian leadership in Ramallah, Abbas claimed that Israeli Prime Minister Benjamin Netanyahu is transferring the money himself, "and we are paying the price."
Abbas also announced that elections will be held for the Palestinian Legislative Council within six months.
