They have fired at "buildings, roads, vehicles", anid it is "practically impossible for the locals to leave the area".
Though not impossible, just difficult.
And There is " no guarantee that they will not be fired at while trying to escape"
I would also assume that "the people are very scared"
It is true that" the air raids started during the night and continue"
The only possible point of contention is that "there are no Hezbollah activists in Qana" and a hezbolla activist is far different than an active participant in the war.
