SEOUL, South Korea (AP) — A fire likely sparked by exploding lithium batteries has swept through a manufacturing factory near South Korea’s capital, killing 22 mostly Chinese migrant workers and injuring eight. Official say the fire began Monday after batteries exploded while workers were examining and packaging them at the second floor of the factory in Hwaseong city, just south of Seoul. An investigation is ongoing. The dead include 18 Chinese, two South Koreans and one Laotian. China has a sizable ethnic Korean minority and in recent years, some have migrated to South Korea to seek work.
