GAZA CITY: One bucket at a time, Palestinian workers cleared sand and crumbling mortar from the remains of a former medieval fortress turned museum in Gaza City, damaged by two years of fighting between Israel and Hamas. A dozen workers in high-visibility jackets worked by hand to excavate the bomb-damaged buildings that remain of the Pasha Palace Museum — which once housed Napoleon Bonaparte during a one-night stay in Gaza — stacking stones to be reused in one pile and rubble to be discarded in another. Overhead, an Israeli surveillance drone buzzed loudly while the team toiled in silence.
