Several anti-Syrian Lebanese politicians blamed Syria. However, Syrian authorities denied complicity and stated that the crime was aimed at directing fresh accusations against Syria.[1] Commentators stressed that the explosion occurred only a few hours before the UN investigating commission was due to submit an update of its report on the Hariri assassination to then-UN Secretary General Kofi Annan.[14] In response, Lebanese Prime Minister Fouad Siniora announced that he would ask the United Nations Security Council to investigate Syrian complicity in the deaths of Tueni and other prominent anti-Syrian figures.
