(3 Jan 2014) FOR CLEAN VERSION SEE STORY NUMBER: 925059 U.S. Secretary of State John Kerry's closed-door diplomacy to broker peace between Israel and the Palestinians has burst into a public spat, with both sides trading blistering criticisms, Republican senators showing up in Jerusalem to argue Israel's side, and Palestinian demonstrators protesting his visit. Kerry is on his 10th visit to the region to try to craft a peace treaty that would create a Palestinian state alongside Israel. He met for three hours on Friday with Israeli Prime Minister Benjamin Netanyahu. Later in the day, Kerry traveled to Ramallah, West Bank, to speak with Palestinian President Mahmoud Abbas. Although battered by sniping from all sides, Kerry remained upbeat _ at least publicly. Asked if he was making progress, Kerry replied that progress is being made every day. So far, the two sides have engaged in about 20 rounds of negotiations, which have entered a more intense phase. Kerry is asking both leaders to start making tough, highly political decisions in hopes of narrowing differences and agree on a framework that will outline a final peace pact. The goal is for the framework, or series of guidelines, to address all core issues, including borders between Israel and a future Palestinian state, Palestinian refugees and conflicting claims to the holy city of Jerusalem. No agreement on a framework is likely during Kerry's visit.
