<p>Hundreds of documents have been leaked to social media in recent days including testimonies by senior Palestinian Authority (PA) officials to the commission of inquiry established in 2010 to probe the death of former PA chairman Yasser Arafat,&nbsp;<em>Kan 11 News</em>&nbsp;reported Friday.</p> <p>The person who led the probe was Fatah senior official Tawfik Tirawi, and its results were never made public. The&nbsp;<em>Al-Araby Al-Jadeed</em>&nbsp;newspaper on Friday quoted PA security sources who said that "Palestinian security mechanisms have launched an investigation to find out who is responsible for the leaking of the documents."</p> <p>Tirawi himself admitted in recent days that the documents were leaked and added that "the documents remained secret to maintain the integrity of the investigation until the full truth is discovered." According to the documents, during the investigation, 302 people were summoned to testify about Arafat's death. From the testimonies in the leaked documents, it emerged that relations between Arafat and his successor as PA chairman, Mahmoud Abbas, were tense in the period before Arafat’s death.</p> <p>According to one of the testimonies quoted by&nbsp;<em>Kan 11 News</em>, Arafat turned to Abbas and asked him for assistance in lifting the Israeli blockade of the Mukataa in Ramallah, to which Abbas replied, "He who gets into trouble should know how to get out of it", a reference of Arafat's support for the intifada.</p>
