A landslide toppled an elementary school building in a southwest China's Yiliang County on Thursday, burying 18 pupils and killing at least five people. Another victim was buried in a house, and one person was seriously injured in the landslide Xinhua said. The landslide destroyed the Tiantou Elementary School and hit two farmhouses in Zhenhe village around 8am. More than 800 people were relocated, and about 2,000 people were trying to rescue the students. The area was ravaged by an earthquake last month that killed 81 people and devastated several villages. Thursday was a holiday across China, but students were in school to make up for days missed after the quake.
