Commemorations in the West Bank have marked the 2004 demise of the former head of the Palestinian Authority, Yasser Arafat.

The Thursday anniversary in the city of Ramallah in central West Bank was attended by thousands of Palestinians, AFP reported.

Arafat died in a French hospital in mysterious circumstances. The medical authorities withheld information about his disease and the cause of death.

Bassam Abu Sharif, one of Arafat’s former advisors, has claimed that Israeli spy agency Mossad had poisoned him through his medications.

Arafat had spent years under a Tel Aviv siege in Ramallah.

Addressing the mourning crowd, Sayed Nasser Arafat al-Qudwa, Arafat’s nephew and a former Palestinian representative to the United Nations, said Israel had a role in his death.

Palestinians were determined to pursue "the last piece of evidence in the assassination," he said.

There have also been reports suggesting a United States-Israeli plot to assassinate Arafat by senior officials from the Fatah party, founded by Arafat, which represents the largest faction in the umbrella group of the Palestine Liberation Organization (PLO).

PLO’s Executive Committee has dismissed the claim as a Tel Aviv plot.
