Salaam Fayyad, who resigned on Saturday, was seen as one of the Palestinians’ most moderate and respected figures. Kerry called Fayyad a “good friend” who made a big difference for the Palestinians. Fayyad’s resignation comes as Kerry works to revive the Israeli-Palestinian peace process. Kerry is trying to help revitalize the Palestinian economy and Fayyad was expected to play a major role. Kerry said Sunday in Tokyo that he believed Fayyad would still play a role in Palestinian politics. Fayyad and Palestinian President Mahmoud Abbas (mahk-MOOD’ ah-BAHS’) had been in dispute over the extent of the prime minister’s power.
