Five people have been killed, including two police officers, in a shooting in rural northern China.

The shooting early Tuesday in Suning county marked a rare incidence of gun crime in China, where private ownership of firearms is illegal.

The official Xinhua News Agency said the gunman, 40-year-old Liu Shuangrui, who was among those killed, suffered from paranoid schizophrenia. It said he turned a double-barreled shotgun on his neighbors, killing two of them, before police arrived at the scene.

Two officers were then shot to death, including the political commissar of the county police department, before Liu was shot and killed.

Xinhua said five other people were injured in the shooting. A Suning police officer reached by phone said she had no information about the case.
