With no end in sight to Israel’s air blitz, the humanitarian situation in Gaza is going from bad to worse.As hospitals struggle to cope, a fraction of those hurt have been able to cross into Egypt for treatment. But most of the population remains in what is left of their surroundings. Israel says the onslaught is aimed at putting a stop to Palestinian rocket attacks that intensified after a truce with Hamas expired. But Palestinians salvaging their remaining belongings, see things very differently. “There is the result of the Zionist attack on Gaza” said one man outside what was once his home. “We no longer have a house because of the bombardments. We need a safe shelter.” As people queued for bread, Israel announced that a convoy of 109 trucks carrying international humanitarian supplies had been authorised to enter Gaza today. The enclave, where most of the population depend on foreign aid, has been virtually sealed off by Israel since Hamas seized control in June last year.
