[JURIST] German prosecutor Detlev Mehlis Monday submitted a new report to the UN Security Council on the February bombing assassination of former Lebanese Prime Minister Rafik Hariri [JURIST news archive], including additional evidence of Syrian involvement in the murder. Mehlis will brief the Council Tuesday on the latest report of his ongoing investigation [UN materials], the text of which has not yet been publicly released. Quoting from a copy, however, French press agency AFP says that a comprehensive deposition by a new witness "strengthens the evidence confirmed to date against the Lebanese officers in custody, as well as high-ranked Syrian officers." Mehlis has recommended that the probe be extended for an additional six months [UN News report] to gather more information, although he himself is stepping down. AFP has more.
