A spokesman for the U.N. tribunal investigating the assassination of a former Lebanese prime minister says it will be weeks before the details of expected indictments are made public.

The Netherlands-based court is expected to issue its first indictments as soon as this month in the 2005 killing of Rafik Hariri.

But a court spokesman, Crispin Thorold, said Wednesday that the contents will remain confidential until confirmed by the pretrial judge, which could take "at least six to 10 weeks" from the time the indictments are submitted.

The possibility that Hezbollah members could be charged has raised fears of new violence in Lebanon. The Shiite group controls the most powerful military force in the country and is also politically influential.
