Egyptian President Hosni Mubarak met with Lebanese Prime Minister Saad el-Hariri Thursday and discussed bilateral relations and regional issues. In his visit to Cairo, the first since taking office in November, Hariri also discussed domestic Lebanese political developments with the Egyptian president, Egypt's official Middle East News Agency (MENA) reported. The Lebanese premier met his Egyptian counterpart, Ahmed Nazif, on Wednesday night for talks aimed at boosting economic and energy ties. A pipeline linking Egypt's natural gas refineries with the Lebanese city of Tripoli came online in October, with supplies being used at a nearby power plant. The Lebanese Foreign, Economy and Information ministers, who are accompanying Hariri, also met with their Egyptian counterparts.
