The man accused of killing a doctor and injuring two other medical workers in one of the most notorious attacks caused by a medical dispute stood trial on Wednesday on the charge of intentional homicide.

Lian Enqing, 33, is suspected of stabbing to death Wang Yunjie, 46, and severely wounding two other physicians at the First People's Hospital of Wenling in Zhejiang province in October. It is believed he was unhappy with a surgery done on his nose at the hospital.

The attack caused medical worker sit-ins at a number of hospitals in east China in the following weeks. They called for more care for doctors and an end to attacks. The crime and several other incidents had prompted China's top security body to urge a severe crackdown on crimes targeting medical staff.
