Media Backspin links to some recent AP and AFP pictures of Gaza, showing buzzing markets and well-stocked supermarkets, backing up what the JC's own stringer in Gaza, Moeen Elhelou, wrote a couple of weeks back. While not all foods may be available, there is no food shortage per se.
As a side-note, it is interesting to see how many of the products in the pictures are labelled in Hebrew and are clearly imported from Israeli suppliers. If the Israelis are out to starve the people of Gaza, as its enemies allege, they are going about it in a very strange way.
