Day 2 of Lebanon's new civil war

In a few hours of fighting between the Lebanese army and the  followers of salafi fanatic Sheikh Ahmad Assir,  12 soldiers lay dead.  Conflicting figure on number of  injuries suffered by the military and there are conflicting reports of salafi deaths.  One forum says,  not a single Sunni was killed by Lebanese fire ... that's very, very doubtful.

Why do I get this feeling that the Lebanese army's heart is not in the fighting ?   Is the army made up of mostly Sunnis with a sprinkling of Christians and the Sunnis are not aiming to kill their fellow Sunnis?  How many of the soldiers killed were actually Lebanese Christians?  How many were Shiites? Something's not right.
This post will be updated if I get a proper count of  the Sunni dead. Simply can't  believe that only the army blokes were blown away.
