Emergency teams in China’s southwestern Sichuan province battled against time Sunday to locate 28 people missing after a rain-triggered landslide killed one person and buried homes.

Nearly 1,000 personnel, including armed police, firefighters and medical professionals, continued to work in the rescue operation following the landslide in the village of Jinping in Junlian county on Saturday. Some officers navigated through the remains of collapsed buildings, using drones and life-detection radars to locate any signs of life with the help of local officials who were familiar with the area, state broadcaster CCTV said.
