Al-Jazeera released these documents in January 2011. Their website states,
"Over the last several months, Al Jazeera has been given unhindered access to the largest-ever leak of confidential documents related to the Israeli-Palestinian conflict. There are nearly 1,700 files, thousands of pages of diplomatic correspondence detailing the inner workings of the Israeli-Palestinian peace process. These documents – memos, e-mails, maps, minutes from private meetings, accounts of high level exchanges, strategy papers and even power point presentations – date from 1999 to 2010.
The material is voluminous and detailed; it provides an unprecedented look inside the continuing negotiations involving high-level American, Israeli, and Palestinian Authority officials."
