At the rally marking four years since the death of Yasser Arafat, the first president of the Palestinian Authority, Arafat's nephew, Nasser al-Qidwah, said that the circumstances surrounding his uncle's death will soon come to light, emphasizing that he believed that Arafat had been poisoned by Israel.

Speaking to the French news agency AFP, al-Qidwah said that "every day there are statements and clues about the elimination of Arafat and every day we draw closer to the poisoning theory."

"In a year or two, the nature of the poison administered to Yasser Arafat and the procedure used will be known," Qidwah added. "In any case, Israel is responsible for his death. There were preparations to get rid of the political leadership of the Palestinian people."

He went on to say that though there was no solid proof of the poisoning, he was gathering information on the subject.

While more than 10,000 people attended the memorial service in the West Bank city of Ramallah, no such service was held in the Gaza Strip. Fatah and other groups said they submitted requests to the Hamas authorities in the Strip for permits to hold commemoration rallies, but they were never given a response. Hamas, on the other hand, said no such requests were made.

Last year, more than 250,000 Palestinians attended the rally in Arafat's memory, during which Hamas police officers killed seven people.
