More than 100 people were working at the site in Hwaseong city, just south of Seoul, when the blaze tore through it on Monday morning.

Forensic and other experts were combing through the charred ruins of a factory building near South Korea’s capital on Tuesday to find the cause of a devastating fire that killed 23 people, mostly Chinese migrant workers, in one of the country’s deadliest blazes in years.
