Israeli settlers have uprooted more than 7,000 Palestinian olive trees this year (VIDEO)

Human rights campaigners say Israeli settlers have uprooted more than 7,000 Palestinian olive trees this year. That is down on last year, but farmers say they are still frequently attacked and harassed. In the Occupied West Bank, foreign volunteers are joining the harvest, hoping their presence will help protect farmers and their trees. Al Jazeera's Nicole Johnston reports from Biddo.
