DHAKA: A man armed with a knife has killed seven people at a hospital in north-eastern China, state media report.

The attack took place on Thursday in the popular resort town of Beidaihe, state broadcaster CCTV news said, reports the BBC.

The 27-year-old suspect was believed to be suffering from a mental illness and has been arrested, it added, giving no motive for the attack.

A hospital administrator was among those killed, and a nurse was injured in the attack, local media also said.

The incident comes as the latest in a series of stabbing attacks across China.

In September, four children were killed by a man while on their way to school in China's southern Guangxi Zhuang autonomous region.

Another knife attack that same month saw three children killed and six people injured in a knife attack at a school in the central Hubei province.

In recent years, China has also seen a rise in the number of attacks on doctors and nurses by people who blame them for the deaths of relatives.
