CAIRO (Reuters) - Lebanon Prime Minister Saad al-Hariri said late on Friday he is on his way to the airport in Saudi Arabia.  Hariri, who sparked a crisis by resigning as Lebanese prime minister on Nov. 4 during a visit to Saudi Arabia, tweeted,  To say that I am held up in Saudi Arabia and not allowed to leave the country is a lie. I am on the way to the airport...    Earlier a member of his party said Hariri will leave Riyadh for France on Friday, but will not return directly to Beirut after the visit.  Hariri s abrupt resignation while he was in Saudi Arabia and his continued stay there caused fears over Lebanon s stability and thrust it into the bitter rivalry between Riyadh and Iran.
