Wednesday, a bomb exploded in Beirut, killing 64-year-old Antoine Ghanem of the right-wing Christian Phalange Party and four other people. He had only returned to Lebanon from refuge three days earlier.
Prime Minister Fouad Siniora has asked the United Nations to help investigate Ghanem's slaying.
His funeral is scheduled for Friday, which the government declared a day of mourning, the report said.
