Israeli news sources have marked the beginning of the latest intifada as July 2014, corresponding with the murder of Mohammed Abu Khdeir, a sixteen-year-old Palestinian who was kidnapped and burned alive by Jewish extremists — a retaliatory attack following the kidnapping and murder of three Israeli teenagers. Three weeks later, thousands of Palestinians marched from Ramallah toward Jerusalem. Protesters were stopped and confronted by Israeli border guards near the Qalandiya checkpoint where violence erupted, leaving 200 Palestinians wounded and two dead. A notable increase of attacks in Jerusalem was observed by Israeli security sources in the aftermath of the Khdeir murder and Israel's Operation Protective Edge on the Gaza Strip.
