A UN-backed tribunal on Tuesday finds the main defendant, Salim Jamil Ayyash, guilty of bombing that killed former Lebanese premier Rafik al-Hariri. Ayyash was a member of the Iran-backed Hezbollah group, and according to prosecutors, he used a cellphone which was critical in the attack. However, the tribunal said there was no evidence that “the Hezbollah leadership” or Syrian regime were involved in the assassination.
