Pope Francis has called for more people to donate their organs in a bid to stop illegal trafficking, but spoke out against the legalization of the organ market, Rome's mayor said Saturday.

A Middle East Airlines flight from Geneva arrived in Beirut on Sunday after landing in Rome over the absence of a passenger, the airline announced.

U.N. Special Coordinator for Lebanon Derek Plumbly warned that the vacuum in the presidency would impact the international community's trust in Lebanon.

President Michel Suleiman is expected to head on Friday a cabinet session at the Baabda Palace after he returns from Rome, where he attended the canonization mass of Popes John Paul II and John XXIII that was held at the Vatican.
