The visit of a Libyan delegation to Beirut this week marks an “important step” in the disappearance of Imam Musa Al Sadr, a prominent Lebanese Shiite cleric who went missing during a trip to Libya in 1978, a Lebanese judicial source told The National. “This is the first time in years that the Libyan side is showing serious signs of co-operation regarding Mr Al Sadr's case,” the source said. The judicial source said that the current talks were first steps to resume co-operation over the case. In 1978, Mr Al Sadr along with an aide and a journalist flew to Libya to meet local officials. This month, Human Rights Watch called for the release of Mr Qaddafi.
