Kerry back to Israel as Palestinians warn of negotiations 'failure'

US Secretary of State John Kerry delivers the keynote address at the
Saban Forum in Washington on Dec. 7, 2013 

The announcement came after Yasser Abed Rabbo, a top official with the Palestine Liberation Organization (PLO), on Monday said that Kerry's ideas on the future configuration of security arrangements which were presented to the Palestinian leadership last week, had provoked a "real crisis".

"These ideas will drive Kerry's efforts to an impasse and to total failure because he is treating our issues with a high degree of indifference," he told AFP. 

The proposals focus on security arrangements in the Jordan Valley which runs down the eastern flank of the West Bank, with commentators saying it would allow Israel to maintain a long-term military presence there.
