(CNN) - At least 28 people were killed and 113 wounded on Saturday evening when a group of people armed with knives stormed a railway station in the southwest Chinese city of Kunming, according to state news agency Xinhua, citing authorities.
It was an organized, premeditated terrorist action involving more than 10 attackers, authorities told the news agency. Five suspects were shot to death and the hunt continued for others, according to authorities.
People were attacked at the station square and ticket hall, Xinhua said in an update early Sunday.
No motive has been provided. Chinese President Xi Jinping urged law enforcement "to investigate and solve the case and punish the terrorists in accordance with the law," according to Xinhua.
"I saw a person come straight at me with a long knife and I ran away with everyone," he said, adding that people who were slower were severely injured. "They just fell on the ground."
He said he sustained injuries to his chest and back.
The news agency reported that several suspects had been apprehended, and questioning at the site continued.
Doctors were seen transporting injured people to a hospital, the news agency reported.
A doctor with Kunming No.1 People's Hospital told Xinhua over the phone they're not sure of the number of casualties.
Xinhua said the Kunming railway station is one of the largest in southwest China.
The news agency quoted a 50-year-old woman whose older husband was among those killed.
"Why are the terrorists so cruel?" said Chen Guizhen, holding her husband's bloodied ID card.
