A heap of plastic leg sockets rests on a shelf. Palestinian technicians in white lab coats scurry past.
They slip into side rooms to sand down leg molds, mix chemicals, cut and polish plastics with big machines, and screw together rods. Tables and floors are speckled with white plaster. Saws and hammers hang from the walls.
"This is the workshop," says Mohammed Dwema, director of the Artificial Limbs and Polio Center in Gaza City.
The clinic is creating prosthetic legs from scratch for the first round of young Palestinians who lost a leg to an Israeli soldier's bullet during recent protests at the Gaza-Israel border.
