Lebanese judicial officials say the son of late Libyan leader Moammar Gadhafi will be questioned by a judge investigating the disappearance of a top Shiite cleric while on a visit to Libya in 1978.

The officials say Judge Zaher Hamadeh has asked that Hannibal Gadhafi be brought to the Justice Palace to check whether he has information about Imam Moussa al-Sadr.

The officials, who spoke Saturday on condition of anonymity in line with regulations, say Hamadeh wants to check whether Gadhafi has any information about the fate of al-Sadr and two companions who went missing with him.

Gadhafi, who was three in 1978, was briefly kidnapped by militants in Lebanon before they handed him over to police late Friday.

Lebanon has blamed Moammar Gadhafi for al-Sadr's disappearance.
