A boy walks past boats docked at the entrance gate of the fishermen's village in the El Max area of the Mediterranean city of Alexandria September 12, 2014.

While the government has tried to fix the state's bloated finances by cutting subsidies and reining in spending, some argue the reforms hurt Egypt's most vulnerable who have long relied on a generous system of fuel and food subsidies to supplement low incomes.
