Former prime minister Saad al-Hariri made a rare visit to Leba**n overnight and will make a speech marking the 10th anniversary of his father's assassination on Saturday, Lebanese media said. His father, Rafik al-Hariri, was killed in a 2005 Beirut waterfront bombing that almost tipped the country into civil war. Saad al-Hariri, Leba**n's most influential Sunni politician, left the country in 2011 after his government was toppled by a coalition including the Iranian-backed Shi'ite group Hezbollah.
