A South Korean man tending a family grave is suspected of sparking one of the ‘unprecedented’ wildfires that ravaged the southeastern part of the country last week, the National Police Agency said Monday.

South Korean police plan to question a 56-year-old man on suspicion of starting at least one of the wildfires that recently devastated the country’s southern regions, killing 30 people and burning more than 119,

A combination of an aging society and a reliance on temporary workers meant older people were disproportionately on the frontlines tackling South Korea's devastating wildfires this week - and paid a disproportionate price.
