NEW YORK CITY: The head of the UN Development Programme said on Tuesday that living conditions in Gaza are the worst he has witnessed in his career, as he urged Israeli authorities to grant more access for the removal of debris, the provision of temporary housing, and private-sector recovery efforts. Speaking in East Jerusalem after a three-day visit to Gaza, Alexander De Croo said 90 percent of the territory’s population was living amid rubble in “extremely painful” and dangerous circumstances.
