The Palestinian Ministry of Health identified the deceased as 18-year-old Mahmoud Nakhleh, who was shot in the abdomen during a protest against the Israeli army in the al-Jalazun refugee camp on Friday.
According to Maan, a local Palestinian news agency, Israeli soldiers shot Nakhleh from a distance of fewer than 10 metres.
The soldiers tried to detain Nakhleh afterwards, Maan reported, but Palestinian paramedics were able to take him after a standoff that lasted more than 30 minutes. Nakhleh was transferred to a hospital, where he was pronounced dead.
Fadwa Safi, a resident of the Jalazun camp, told Al Jazeera that the soldiers dragged Nakhleh and beat him up. The 42-year-old was in her home when her sister called to say there was a boy who was injured by a bullet and was being dragged by the army.
"I stepped out of my home and then I saw them carrying him and beating him while he's injured," Safi said. "Four soldiers were dragging him and there were around seven additional soldiers walking with them."
"I ran after them," she continued. "They threw a sound grenade at me and told me to go home, but I said I'm not going - I want the boy because he still had life in him, he was still breathing and moving. They threw him on the ground."
Safi said the ambulance was already present but that the soldiers wouldn't let it enter the camp at first.
"One soldier pointed his rifle at me," she said. "I told him: shoot me, I want the boy."
"I had hoped to save him and I couldn't," she wept. "I was happy when I took him [because I thought] he could be rescued. I didn't know he was dying."
The Israeli army did not immediately comment on the teen's death.
According to the Palestinian Prisoners' Club, at least 100 Palestinians have been arrested over the past 24 hours. Four Palestinians were killed by Israeli forces in separate operations overnight on Wednesday and on Thursday afternoon.
