ISTANBUL  Gaza has become home to the highest number of child amputees per capita worldwide since the start of Israel’s war, the head of the UN agency for Palestinian refugees (UNRWA) said Wednesday. UNRWA Commissioner-General Philippe Lazzarini said that up to 4,000 amputations were reported in Gaza since October 2023. “The toll on children and childhood is beyond just the physical injury and the spreading hunger. Children’s scars are deep and invisible: anxiety, nightmares, aggression, fear.
