According to an Arabic investigative journalism website , Assange had received money from semi-official Israeli sources and promised them, in a “secret, video-recorded agreement,” not to publish any document that may harm Israeli security or diplomatic interests.
The sources of the Al-Haqiqa report are said to be former WikiLeaks volunteers who have left the organisation in the last few months over Assange's “autocratic leadership” and “lack of transparency.”
In a recent interview with the German daily Die Tageszeitung, former WikiLeaks spokesperson Daniel Domscheit-Berg said he and other WikiLeaks dissidents are planning to launch their own whistleblowers' platform to fulfil WikiLeaks's original aim of “limitless file sharing.” 
Mr Domscheit-Berg, who is about to publish a book about his days 'Inside WikiLeaks', accuses Assange of acting as a “king” against the will of others in the organisation by “making deals” with media organisations that are meant to create an explosive effect, which others in WikiLeaks either know little or nothing about. 
Furthermore, Assange's eagerness for headline-grabbing scoops meant that WikiLeaks had not been able to 'restructure' itself to cope with this surge of interest, insiders add. This has meant that smaller leaks, which might be of interest to people at a local level, are now being overlooked for the sake of big stories. 
According to the Al-Haqiqa sources, Assange met with Israeli officials in Geneva earlier this year and struck the secret deal. The Israel government, it seems, had somehow found out or expected that the documents to be leaked contained a large number of documents about the Israeli attacks on Lebanon and Gaza in 2006 and 2008-9 respectively. These documents, which are said to have originated mainly from the Israeli embassies in Tel Aviv and Beirut, where removed and possibly destroyed by Assange, who is the only person who knows the password that can open these documents, the sources added.
Indeed, the published documents seem to have a 'gap' stretching over the period of July - September 2006, during which the 33-day Lebanon war took place. Is it possible that US diplomats and officials did not have any comments or information to exchange about this crucial event but spent their time 'gossiping' about every other 'trivial' Middle-Eastern matter?
Following the leak (and even before), Israeli prime minister Benjamin Netanyahu said in a press conference that Israel had “worked in advance” to limit any damage from leaks, adding that “no classified Israeli material was exposed by WikiLeaks.”  In an interview with the Time magazine around the same time, Assange praised Netanyahu as a hero of transparency and openness! 
According to another report , a left-leaning Lebanese newspaper had met with Assange twice and tried to negotiate a deal with him, offering “a big amount of money”, in order to get hold of documents concerning the 2006 war, particularly the minutes of a meeting held at the American embassy in Beirut on 24th July 2006, which is widely considered as a 'war council' meeting between American, Israeli and Lebanese parties that played a role in the war again Hizbullah and its allies. The documents the Al-Akhbar editors received, however, all date to 2008 onwards and do not contain “anything of value,” the sources confirm. This only goes to support the Israel deal allegations.
Finally, it might be worth pointing out that Assange might have done what he is alleged to have done in order protect himself and ensure that the leaked documents are published so as to expose the American hypocrisy, which he is said to be obsessed with “at the expense of more fundamental aims.”
"The story was picked up by a writer at IndyMedia UK, who, citing Al Haqiqa, said that Israel learned that the documents contained information about about the Israeli attacks on Lebanon and Gaza in 2006 and 2008. These documents were destroyed by Assange at the request of the Israelis, according to the anonymous writer."
