An attack by knife-wielding men at a railway station in Kunming in south-west China has left at least 28 dead, the state news agency Xinhua says.
Nothing is known so far about the motivation behind the attack, in which 113 people are said to have been hurt.
However, authorities described it as an “organised, premeditated, violent terrorist attack”.
Five suspects were shot dead but their identities have not been confirmed, Xinhua said.
Witnesses said that the men attacked people at random.
A survivor named Yang Haifei, who was wounded in the back and chest, told Xinhua he had been buying a train ticket when the attackers, most of them dressed in black, rushed into the station.
“I saw a person come straight at me with a long knife and I ran away with everyone,” he said.
