The killing of an emergency doctor during a house call in Inner Mongolia on Saturday has again raised concerns about medics' safety.

Baogang Hospital in Baotou, the Inner Mongolia autonomous region, said on its official website that Zhu Yufei, 34, a woman doctor in its neurology department, was killed while on a home visit on Saturday.

According to the hospital, at 1:42 am it received a call from the city's emergency medical center reporting that a woman was experiencing convulsions and needed immediate help. When Zhu, the doctor in charge, and three medics arrived at the scene, a man, suspected to be Li Xinglong, attacked them with a cooking knife, locked the three medics outside, and allegedly killed Zhu in the house.
