Wikipedia is one of the most visited websites in the world but, by the admission of some of its own volunteer editors, it suffers from a persistent problem - terrible pictures, particularly of celebrities.It is so full of notable people with very old or unflattering photographs that there are even Instagram accounts dedicated to

Under the present GHF distribution system there currently are four known sites."By and large, it's designed to dramatically increase the concentration of the population by having the only sources of food remaining in a very small number of places," said Chris Newton, a senior analyst at the Brussels-based think tank Crisis Group.

"You either follow all their rules and probably survive in a small radius around these sites or you are very unlikely to survive."The presence of armed security and Israeli soldiers at or near the distribution sites has also alarmed experts, who said it undermined faith in aid operations.
