What has happened in Gaza?

Gaza is facing its worst humanitarian crisis in more than 40 years. A new report by aid agencies and humanitarian groups says things haven’t been this dismal since Israel’s 1967 occupation. It says the Israeli blockade has left more than one million Palestinians isolated, dealing with poverty, dealing with unemployment, with little access to education and healthcare services. It found water and sewage systems are on the verge of collapse. Israel blames the hardships on Hamas militants who keep firing rockets into Israel.
