According to reports by Palestinian media, the 26-year-old had been involved in a campaign to protect farmers from Israeli settler violence.
It comes after Israeli forces withdrew from Jenin city and its refugee camp in the occupied West Bank, following a major nine-day operation there.
During the operation, at least 36 Palestinians were killed – 21 from Jenin governorate – the Palestinian health ministry says. Most of the dead have been claimed by armed groups as members, but the ministry says children are also among those killed.
In the past 50 years, Israel has built settlements in the West Bank and East Jerusalem, where more than 700,000 Jews now live.
Settlements are held to be illegal under international law – that is the position of the UN Security Council and the UK government, among others – although Israel rejects this.
