In a modest makeshift workshop tucked inside the crowded Nuseirat refugee camp in central Gaza, the soft sound of an oud echoes through the ruins of war. Surrounded by wooden pallets, fragments of crates that held humanitarian aid, and the pieces of damaged instruments, Palestinian craftsman Suhail Abu Shawish bends carefully over a battered oud, tuning its strings after days of painstaking repair. The treasured instrument -- scarred by shelling and destruction during the war in Gaza -- is one of many that have found their way to his workshop.
