Arun Gandhi was quoted saying he wants "to promote the philosophy of non-violence, the approach that non-violence is the only venue that can solve our problems."
He said he will focus his efforts on persuading the Palestinians to abandon violence in the quest for statehood.
"I understand that many bad things happened 55 years ago, but the attempt to get justice by revenge accomplishes nothing," he told Haaretz.
Gandhi will speak at three rallies being planned in the West Bank towns of Ramallah, Abu Dis and Bethlehem Aug. 26. His campaign is being organized by Palestinian non-governmental organizations, including those opposed to Israel's security barrier along the West Bank and activists linked to Yasser Arafat's Fatah faction.
Gandhi is the head of the M.K. Gandhi Institute for Non-violence in Memphis.
