NEW YORK CITY: Olga Cherevko has spent the past several months crisscrossing Afghanistan, from Bamiyan and Herat to Paktika, Khost and, most recently, Nuristan, where flash flooding recently tore through villages, leaving families with nothing. Across different landscapes and provinces, the stories were the same. “People tell me they’re exhausted,” said Cherevko, spokesperson for the UN Office for the Coordination of Humanitarian Affairs in Afghanistan.
