A fire at a factory in central China on Monday killed dozens of people, according to Chinese state media, the latest in a string of fatal industrial accidents to hit the country in recent years.
The official Henan Daily newspaper reported on Tuesday that two previously missing people were found dead following the fire at the Anyang factory in Henan province, raising the death toll to 38.
Two other people were being treated for minor injuries, state broadcaster CCTV reported on Tuesday.
Police arrested an unknown number of suspects in connection with the blaze, which took firefighters almost seven hours to put out, according to CCTV.
Preliminary findings say the fire was caused by violations of electric welding protocols, Henan Daily reported, citing authorities.
China has seen a string of industrial accidents in recent years that have claimed dozens of lives, raising concerns about public safety.
In 2015, at least 173 people died after a series of explosions at a chemical warehouse in the northern port city of Tianjin.
Last October, at least three people were killed and more than 30 injured in a powerful explosion at a restaurant in the northeastern city of Shenyang. The gas explosion occurred in a mixed-use residential and commercial building.
And in June this year, at least one person was killed after a fire broke out at a petrochemical complex in Shanghai.
