27 people were killed and 109 others injured (as of press time) after a group of unidentified armed men stormed a railway station of Yunnan's provincial capital Kunming on Saturday night, the city's police said.

The Ministry of Public Security has dispatched teams to Kunming to investigate.

Police sealed off Kunming's railway station after the attack. Bloodstains could be seen in the ticketing hall, which was strewn with luggage.

Many people with stab wounds were being treated when a China Daily reporter arrived at the Kunming No 1 People's Hospital around 11 pm. Many of the injured were migrant workers, including elderly people and children.

Chen Guizhen said at the hospital that she saw her husband killed by three men wearing masks. The woman, who is in her 50s, and her family members were sitting at the railway station square when the masked attackers came to the seats next to them. Suddenly, the men pulled out knives hidden inside their coats and attacked her husband.

After 11:30 pm, "irrelevant people" were not allowed in the hospital. Beijing Street — one of the city's main streets, which runs in front of the railway — was reopened to pedestrians at around 11:40 pm, while vehicles were still not allowed to enter.

Yunnan's Party secretary Qin Guangrong rushed to the scene before 11 pm to guide the rescue work and investigation. Local TV station K6 asked people to donate blood for the injured.
