A special U.N.-backed tribunal on the assassination of former Lebanese Prime Minister Rafik Hariri has fined the manager of a local TV station for not removing information about identities of confidential witnesses in the long-running probe.

The Netherlands-based court ruled in August that Al-Jadeed TV's deputy director, Karma Khayat, was guilty of failing to remove information about the witnesses from the network's website and YouTube once she was asked by the court to do so.

Judge Nicola Lettieri said on Monday that Khayat will have to pay 10,000 euros ($11,195) before the end of October.

Outside the TV's offices in Beirut, dozens of people gathered in solidarity with the station.

The 2005 suicide bombing that killed Hariri and 22 others was one of the Middle East's most dramatic political assassinations.
