BEIRUT (Reuters) - Saudi Arabia said on Wednesday it had abandoned mediation efforts in Lebanon between Hezbollah and Saad al-Hariri over the killing of his father and warned that the countrys future was at stake. Saudi Arabia and Syria had worked for months to resolve a dispute between Hezbollah and Hariri over indictments in the 2005 killing of former prime minister Rafik al-Hariri, which are widely expected to accuse Hezbollah members. Saudi Foreign Minister Prince Saud al-Faisal said the kingdom had abandoned its efforts and that the situation in Lebanon was dangerous. If the situation reaches separation or partition of Lebanon, this means the end of Lebanon as a state that has this model of peaceful cohabitation between religions and ethnicities and different groups, he told Al Arabiya television. It would be a loss for the whole Arab nation.
