UDIN DHUNGA, Nepal (AP) — Hundreds of people were reported missing after an avalanche of ice and rock triggered massive flash floods that swept through parts of Nepal on Wednesday, killing at least eight people and causing widespread damage to villages and infrastructure. Officials said 384 tourists, including 291 from countries including India, the United States, the United Kingdom and Malaysia, were reported missing as a result of the flash flood. The Bhotekoshi River flooded around 9 a.m. Wednesday, destroying several villages as well as roads and hydropower projects, officials said. They issued warnings to residents of several of Nepal’s districts and asked them to stay away from the banks of Bhotekoshi, Trishuli and Narayani rivers. “We have asked both India and China to help us with the rescue efforts,” said Sasmit Pokharel, a spokesperson for the Nepali government.

The worst affected area, Rasuwa district, witnessed similar flash floods to those in August last year, when a glacial lake in neighboring Tibet overflowed as a result of high temperatures in the mountain region. Nine people lost their lives and critical infrastructure including a bridge connecting the two countries were damaged at the time.Climate experts at the Kathmandu-based International Centre for Integrated Mountain Development say an avalanche from a glacier likely caused Wednesday’s flash flood.
