Especially considering they probably knew damn well that the Hezzies were launching rockets from there.
I am not saying this is a staged event - more likely caused intentionally by Hezb - however, one should remember that this is
the place where a similar incident in 1996 forced Israel to suspend an operation into Lebanon.
The officer estimated that Qana was being used by the Hizbullah to fire rockets at Israel due to the symbolism in the village. In 1996, Israel was forced to suspend Operation Grapes of Wrath against the Hizbullah after artillery shells killed over 100 Lebanese refugees seeking refuge in a UN building in the village.
