JERUSALEM – Secretary of State John Kerry will return to Jerusalem on Thursday for his fifth visit in less than three months, amid reports of a possible breakthrough in peace talks between Israeli and Palestinian leaders.

Analysts note that there are still many obstacles to serious peace negotiations, not least of which is opposition from within the Israeli government.

But Israel’s Hebrew-language press reported this week that both Israeli Prime Minister Benjamin Netanyahu and Palestinian Authority Chairman Mahmoud Abbas have agreed to a series of concessions that one American diplomat called “exciting.”

According to the reports, Netanyahu’s goodwill gestures include freeing more than 100 Palestinian prisoners in Israeli jails and freezing all new construction outside the Jewish settlement blocks in the West Bank. Abbas, meanwhile, would drop his request for Israel to officially and publicly declare that the peace talks are being conducted on the basis of the 1967 border lines.

“This is very exciting. This is, well, it would be the first real progress or step forward on the peace talks in years,” said the American diplomat, who spoke on the condition he not be named because he’d been told to keep details of the peace talks out of the news media. “We really need to see these kinds of concessions to keep the momentum going in the right direction.”

He said that Kerry was trying to hold three-way, direct talks with Netanyahu and Abbas in Amman, Jordan, next week. If Kerry succeeds in putting together a meeting, it would be the first time in nearly three years that the senior Israeli and Palestinian leaders have sat face to face to discuss peace.

“The shuttle diplomacy that we have been conducting hasn’t worked until now,” said the diplomat, noting the irony of Kerry relaying messages between Netanyahu and Abbas when the governments’ headquarters in Jerusalem and Ramallah, respectively, are less than a 30-minute drive apart. “These two need to sit in the same room and hammer it out.”

Earlier this week, Netanyahu made headlines as he called for “serious talks” with the Palestinians, adding that he would even drive halfway to Ramallah to achieve it.

“If Secretary Kerry, whose efforts we support, were to pitch a tent halfway between (Jerusalem) and Ramallah — that’s 15 minutes away driving time — I’m in it, I’m in the tent,” Netanyahu said. “And I’m committed to stay in the tent and negotiate for as long as it takes to work out a solution of peace and security between us and the Palestinians.”
