RAMALLAH, West Bank – Yasser Arafat's widow says the Palestinian leadership must seek justice for her husband after Swiss scientists found evidence suggesting he was poisoned by the radioactive substance polonium-210.
Suha Arafat spoke to the The Associated Press from Qatar on Thursday after she received the results of an examination of her husband's remains.
Arafat died in 2004 in France, a month after falling ill at his Israeli-besieged West Bank compound. Palestinian officials have alleged Israel poisoned Arafat, a claim Israel denies.
Suha Arafat did not mention Israel, but said Thursday that only countries with nuclear capabilities have access to polonium. She says her husband's death was a crime and that his successors "have to find the tools and pursue the legal case" in international courts.
Palestinian officials plan a news conference Friday.
