At least seven people were killed and 13 others are missing after buildings collapsed in Xiangning County, Linfen City, north China's Shanxi Province, on Friday evening, local media reported Saturday. 

Twenty people have been rescued from the debris.

A landslide was believed to cause three buildings behind a hospital to collapse at the site around 6:10 p.m. local time on Friday, according to the primary investigation. 

Rescue work is still underway and workers face difficulties due to possible secondary disaster risks.
