The Palestinian protester was shot dead at the anti-Israeli demonstration in the occupied West Bank city of al-Bireh adjacent to Ramallah on Friday.
Earlier in the day, several others were injured in similar protests in al-Khalil (Hebron).
Demonstrators also hit the streets in the cities of Nablus, Jenin, Tulkarm and Ramallah.
Israeli forces tried to put an end to the protests by firing plastic and live bullets.
About 1,900 people, including women and children, were killed and nearly 10,000 others injured by the Israeli regime’s massive offensive against Gaza that began on July 8.
Israeli warplanes pounded numerous sites in the Gaza Strip, demolishing houses and burying families under the rubble. Israeli forces also began a ground offensive against the impoverished Palestinian land on July 17.
Nearly 400,000 Palestinian children are in immediate need of psychological help due to “catastrophic and tragic impact” of war, according to the United Nations Children's Fund (UNICEF).
