Saudi king Abdullah Tuesday hailed the election of Egypt's ex-army chief Abdel Fatah al-Sisi to the presidency as an "historic day," calling for a do**rs conference to help Egypt through its eco**mic troubles. The king, whose oil-rich nation is a strong ally of Egypt, said Sisi's sweeping win with 96.9 percent of the vote represents a "historic day and a new stage for Egypt," in a telegram published by Saudi state news agency SPA. "To the brothers and friends of Egypt ... I invite all to a do**rs conference ... to help it overcome its eco**mic crisis," he said. Riyadh pledged billions of dollars in aid to Egypt's new authorities after the overthrow of Islamist president Mohamed Morsi last July.
