RNA - The incident came as the Israeli forces clashed with Palestinians when they raided the Shufat refugee camp situated between three Israeli checkpoints, Maan reported.
The boy was taken to hospital after he was evacuated from the scene, according to reports from the Palestinian Red Crescent.
He was shot in the head with a rubber-coated steel bullet.
The man in his 60s and another resident were treated on the scene after they were shot with rubber bullets. The third internal refugee was not identified.
Several other Palestinians also suffered from severe tear gas inhalation.
Palestinians within the occupied Palestinian territories are routinely victims of violence from Israeli forces.
In August, Israeli Prime Minister Binyamin Netanyahu vowed never to evacuate illegal Jewish settlements in the occupied West Bank, drawing outrage from Palestinian officials.
The right-wing leader's pledge came after a meeting earlier in the day with UN Secretary General Antonio Guterres, who is on a three-day tour in Israel and Palestine to discuss efforts to restart peace talks.
"We have returned here for eternity," Netanyahu said, speaking at a ceremony in the settlement of Barkan in the northern West Bank.
"There will be no more uprooting of settlements in the land of Israel. Settlements will not be uprooted."
