Jassem al-Sadda was killed in the village of Jit, east of Qalqilya, according to medical workers who confirmed his death.
His family said soldiers opened fire on him without warning and prevented ambulance crews from reaching him.
A wave of grief and shock swept through the village as hundreds gathered at the family home to witness the aftermath of the raid, including the bloodstains that covered the floor of Sadda's room.
His mother, Haifa al-Sadda, told Middle East Eye that at around 1am, dozens of soldiers stormed the house without knocking. They immediately broke down the door and entered.
