I am not sure what the answer to that is, but denying people basic human needs, food, water, power, medical suppies is a breach of international law.
As pointed out by people this is 'collective punishment', Palestinians are being punished for the actions of Hamas.
On another note in the west bank restricting access to a mosque for prayer is surely a breach of the human right to practice their relgion so another crime against humanity.
What is to say that some Hamas fighters are not moving south with the population.
What I fear now is a western endorsed blood bath on a horrifc scale.
