Mohammed describes a delivery job from hell.

"I get screwed on every shipment," the Gazan trader told reporters. He said he has to fork out more than $14,000 for each truck of food he brings into the besieged enclave to pay sky-high transport costs, bribes to middlemen and protection from looters. That's up from $1,500-$4,000 before the war began in October.

"It's barely worth my while. But I need food, my neighbors need food, the whole of Gaza needs food."
