If Hezbollah is co-locating with civilians, they're responsible.
SO ISRAEL KILLS THEM AND IT IS SOMEONE ELSES FAULT... Period. Over 150 rockets have been lauched from Qana since hostilities began, that building was an ordnance depot and a launch site, therefore, a legitimate military target.
How do you know??? The investigation by many sides has just begun........
How was Israel to know they had stuffed the basement with civilians? Sure, it could be guessed
I guess you answered you own question...because, well, this is the de able Hezbollah...but, seriously, were they just to let them continue launching rockets from that site until maybe one found an Israel bunker with a similar number of civilians and, then, it would have been okay to obliterate it?
