These terrorists were putting explosives along the border. What do you expect Israel to do? Let them do as they please? If Hamas sends attacks to Israel from civilian positions they -Hamas- must be held responsible for any civilian palestinian casualties; even though Israel always notifies the civilian population that an attack is coming, to avoid as much collateral damage as possible, what military force in the world does that? I remind you that the IDF does not shield itself using Israeli civilians, but nevertheless palestinian terrorists always target Israeli civilians.
