Confidential Palestinian documents leaked to Al Jazeera, the Qatar-based television network, suggest that Mr Obama retreated from a promise that territory occupied by Israel after the Six Day War of 1967 should become the basis for a future Palestinian state.
The documents, part of a second tranche of the “Palestine Papers” released by Al Jazeera on Monday evening, indicate that Mr Obama’s change of heart was the result of Israeli pressure.
