Beijing - A brick wall collapsed onto children at a school in southwest China, hitting six youngsters and killing two of them, an official said on Thursday.
The incident happened around lunchtime on Wednesday at a primary school in Zhenxiong county in Yunnan province.
The wall that collapsed was free-standing and not part of the main school building, said Song Yufeng of the county government's propaganda department. He said too much coal had been piled up on one side of the wall, pushing the wall over.
The six children were around 12 years old, Song said, adding that investigations were continuing.
The safety of school buildings in China has been called into question in the past. Poor design and shoddy construction were blamed for the collapse of many schools during a 2008 earthquake that killed thousands.
