The UN has concluded that Syrian and Lebanese security officials stalked former Lebanese Prime Minister Rafik Hariri for weeks before murdering him in February: UN: Syria, Lebanon Involved in Slaying.

UNITED NATIONS - A U.N. investigation concluded that high-ranking Syrian and Lebanese security officials were involved in the assassination of former Lebanese Prime Minister Rafik Hariri, according to a report released Thursday.

The strongly worded report by chief investigator Detlev Mehlis said the two nations’ intelligence services kept tabs on Hariri before his assassination by wiretapping his phone, and there was evidence a telecommunications antenna was jammed near the scene of the car bomb that killed him and 20 others on Feb. 14.

The decision to assassinate Hariri “could not have been taken without the approval of top-ranked Syrian security official and could not have been further organized without the collusion of their counterparts in the Lebanese security services,” the report said.

Mehlis’ 53-page report accused Syrian authorities of trying to mislead his investigation, and directly accused Foreign Minister Farouk al-Sharaa of lying in a letter sent to his commission.
