Nepal-China flood: hundreds of pilgrims and tourists among the missing

A flash flood triggered by a glacial collapse in the Himalayas has killed more than 160 people on the Nepalese side of the border. Among the hundreds missing are at least 341 foreign nationals, including tourists and pilgrims heading to the sacred Mount Kailash. Videos circulating online show people fleeing the surging wall of water, with some escaping only at the last moment.
