Two people were killed and 21 others were injured in a knife attack at a hospital in Zhenxiong county of China's Yunnan province on Tuesday.

According to state news agency Xinhua, the attack took place at around 11:37 am when a man assaulted people with a knife at a local hospital in the county.
It is not yet known whether police have subdued the suspect, the Hong Kong-based South China Morning Post reported.
Initially, the state media did not specify the nature of the attack, but the CCTV camera footage released on social media shows a person wielding a knife inside the premises of the hospital.

State run news site The Paper published images of a man holding a knife towards another man holding a stick in the hospital lobby, as well as police officers arriving at the scene.
"It happened around 11 in the morning... it's still a bit chaotic, they're still determining the numbers," a local resident told The Paper.
A witness told Red Star News, an online outlet, that he narrowly escaped the attack and that a doctor or doctors were among the injured. Video from the witness showed people who were bleeding and had fallen to the ground, and one older person trying to help another, Red Star social media post said.
Violent crimes of such nature, especially in public places, are extremely rare in China due to their strict firearms policy. While the law strictly prohibits citizens from owning firearms, there have been a rise in the number of stabbings in the past few years.
