At least 18 people were killed and 16 injured when a fire broke out at a martial arts school in central China in the early hours of Friday, according to the local government.
Official state news agency Xinhua reported that all victims were boarding pupils, while local media said they were aged between seven and 16.
The fire had been extinguished and authorities were investigating the cause of the blaze, a statement from the Zhecheng county government in Henan province, said.
Four local officials including the county party secretary were fired over the incident, reported the Henan Daily, a local state-backed newspaper, on Saturday.
Two more suspects were arrested in addition to the school’s manager Chen Lin, the Henan Daily said.
There were 34 boarding students on the premises when the fire broke out, according to government staff quoted by Beijing Toutiao News.
Those hurt, four of whom had severe injuries, were rushed to a local hospital, where an unnamed doctor told local media they were “doing everything they could” to save them.
The cause of the fire was still unclear.
An official confirmed to AFP that the school was the Zhenxing Martial Arts Centre.
Local media reports described it as a “comprehensive martial arts training institution” that aimed to “strengthen the body through morality and martial arts”.
