BEIRUT: A Lebanese delegation headed to Libya Monday as part of ongoing efforts to uncover the fate of Imam Musa Sadr, the National News Agency reported.

The delegation, headed by Judge Hasan Shami, will hold meetings with Libyan officials for a briefing about the developments in the case.

Lebanon's Charge d'Affaires in Tripoli Hasan Saleh will join the delegation upon its arrival in Libya, the state news agency said.

Last month, a source close to the investigation told The Daily Star on condition of anonymity that the trip was part of the continuing joint efforts by the Libyan and Lebanese authorities to reveal the whereabouts of Sadr, the founder of the Amal Movement now headed by Speaker Nabih Berri.

Sadr went missing along with Sheikh Mohammad Yacoub and journalist Abbas Badreddine during a visit to Libya in 1978.

The source said as part of their work the delegation might request questioning former Libyan intelligence chief Abdullah al-Sanousi.

In September, a Lebanese delegation, headed by Lebanese Foreign Affairs Minister Adnan Mansour, paid a visit to Mauritania to question Sanousi, who was a key figure under the reign of late Moammar Gadhafi.

No crucial evidence was declared into the case following Sanousi’s interrogation and the source said the case required further time.

The Mauritanian authorities then handed Sanousi to Libya nearly five months after he was arrested for entering the country illegally.

Since the uprising in Libya, conflicting reports on Sadr’s fate have emerged. Some have claimed that Sadr’s body was found in Libya, but Lebanese officials have said such reports are baseless.

Sanousi, who was considered one of Gadhafi’s closet aides, was detained in Mauritania after he fled following the ouster of Gadhafi.

Berri and Shiite religious leaders have accused Gadhafi of being behind the cleric’s disappearance.
