The Prosecution of the U.N.-backed Special Tribunal for Lebanon announced Tuesday that the Syrian regime was at the heart of the conspiracy that killed ex-PM Rafik Hariri.
At the beginning of its closing arguments at the STL's headquarters in The Hague, the Prosecution also described slain Hizbullah military commander Mustafa Badreddine as the mastermind of the assassination operation.
The Prosecution noted that Badreddine was a senior Hizbullah official and that his military expertise reflected itself in the modus operandi of Hariri's assassination.
It also said that Hizbullah suspect Salim Ayyash led a six-person assassination squad and that there is irrefutable evidence that condemns the four Hizbullah suspects.
Moreover, the Prosecution added that the “green phone network” that oversaw Hariri's assassination fully belonged to Hizbullah.
Prosecutors said their case -- which relies on mobile phone records allegedly showing the suspects conducting intense surveillance of Hariri from just after his resignation until minutes before the blast -- was "circumstantial" but "compelling."
