I don't know who committed the crime in Beirut today but the two sides in the region (the Syrian regime and its followers and the Saudi regime and its followers) are capable of such heinous crimes. But I do believe that Sa`d (mini) Hariri bears the most responsibility: this idiot--literally--thinks that he can enter the game of regime changes in the region and can strike alliances with Jihadi groups to please his masters at Saudi intelligence at no cost to Lebanon.
