The Guardian and broadcaster al-Jazeera have published reports from what has been described as the biggest leak of secret documents in the history of the Middle East conflict.
This latest wave of leaked material in the Guardian is not the result of collaboration with Wikileaks, but through an exclusive partnership with al-Jazeera TV, which obtained the documents.
The Guardian reported this morning that more than 1,600 confidential Palestinian documents had been leaked detailing more than a decade of talks with Israel and the US.
The Guardian reports today that many of the documents - which were drawn up by Palestinian Authority officials and lawyers working for the PLO negotiations support unit - have been independently authenticated by the Guardian and corroborated by former participants in the talks and other sources. The Guardian has supplement its coverage with information from the WikiLeaks US embassy cables relating to the the US consulate in Jerusalem and the US embassy in Tel Aviv.
