A scaffolding collapse at a Beijing high school Monday morning killed 10 people and injured four, Chinese state media reported.

The official Xinhua News Agency said the accident occurred at Tsinghua High School in the city's northwest.

A high school official with the surname Jiang told The Associated Press that all the victims were workers building a school gymnasium. He said no teachers or students were involved.

The official said rescue crews were waiting for equipment able to lift heavy debris before they could clear the site.

Outside the school, Wang Zhiquan said the accident had claimed the life of his nephew Chen Haijun, a 42-year-old migrant worker from northeast Heilongjiang province.

He told reporters he wanted to see the scene in person and wanted proper compensation as Chen's parents were ill. He said the felled worker had two children and was the only one supporting his family.
