(FILES)- A September 28, 1998 file photo shows Palestinian leader Yasser Arafat addressing the 53rd session of the United Nations General Assembly 28 September at the UN in New York. Swiss radiation experts have confirmed they found traces of polonium on clothing used by Yasser Arafat which "support the possibility" the veteran Palestinian leader was poisoned in a report published by The Lancet over the week end of October 12, 2013.
