Nepali rescue workers scoured a debris-strewn ravine Monday for more bodies from the mangled wreckage of a plane with 72 people on board, with hopes of any survivors now "nil", according to officials. The Yeti Airlines ATR 72 plummeted into the steep gorge, smashed into pieces and burst into flames as it approached the central city of Pokhara on Sunday morning, in Nepal's worst aviation disaster since 1992.
