A special U.N.-backed tribunal on the assassination of former Lebanese Prime Minister Rafik Hariri has acquitted a local TV network and its deputy news director of obstructing justice in releasing identities of confidential witnesses in the long-running probe.

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

Judge Nicola Lettieri on Friday scheduled a sentencing hearing for Sept. 28. Khayat could face a prison sentence as well as a fine.

The 2005 suicide bombing that killed Hariri and 22 others was one of the Middle East's most dramatic political assassinations. The trail began last year and is ongoing.
