BEIRUT (AFP) - UN Secretary General Ban Ki-moon will pay an official visit to Lebanon on March 30, a government source told AFP on Friday.

"During his visit, Mr. Ban will be received by (Prime Minister Fuad) Siniora," the source said.

It will be the first trip to Lebanon by the new UN chief, who took over from Kofi Annan on January 1.

Ban is due to visit Egypt on March 23, probably followed by Riyadh where he has been invited by Arab League chief Amr Mussa to attend an Arab summit on March 28 and 29.

Lebanon's four-month-long political crisis will be one of the major topics discussed at the Riyadh summit.
