Nawi was diagnosed with cancer a few months ago.
Having dedicated his life to fighting for the rights of Palestinians in the West Bank, Nawi viewed himself and was seen by some as a warrior of justice and human rights activist.
He was heavily criticized by right-wing activists over the years and was in the midst of a trial after being accused of tipping off Palestinian security forces with information relating to the selling of lands in southern Mount Hebron, breaching a clause from the Oslo Accords that prohibits any involvement by Israelis in the Palestinian security forces.
