The civil defence chief of Lebanon blames the fires on a vast conspiracy to... collect cheap charcoal. Others are not convinced however. Already rumblings are starting to blame the Syria-Iran-Hezbollah Axis which has been active in assassinations of their opposition. If set up the axis, the fires serve a purpose. Lebanon's parliament is about to appoint a President. The razor-thin majority March 14 Alliance has been vowing to replace the pro-Syrian president with a strong anti-Syrian president. The fires, along with the assassinations, could be a message of ill things to come with March 14 does not appoint a moderate as president.
