Abul Gheit delivered a letter from Egypt’s President Hosni Mubarak to the Saudi monarch.
The source did not give the details of the letter but said it likely concerned a summit the two leaders held on Wednesday in the Egyptian Red Sea resort of Sharm el-Sheikh that covered Lebanon’s protracted political crisis.
Lebanon’s political deadlock has left it without a head of state for more than four months.
Parliamentary sessions to vote for a new president were postponed 17 times as the ruling coalition, backed by the West and most Arab states, and the Hezbollah-led opposition, supported by Syria and Iran, failed to settle their differences.
Both sides have agreed on a consensus presidential candidate, but continue to bicker about the make-up of the new cabinet.
