SEOUL, South Korea — Wind-driven wildfires that were among South Korea’s worst ever have ravaged the country’s southern regions, killing 24 people, destroying more than 300 structures and forcing 28,800 residents to evacuate, officials said Wednesday.

The death toll included a pilot who died after a helicopter crashed during efforts to contain a blaze in the southeastern town of Uiseong, one of the hardest-hit areas. The aircraft had no other crew members. Police said that most of the dead are those in their 60s and 70s.

The National Fire Agency said at least 26 people sustained varying degrees of injuries.

An ancient Buddhist temple, houses, factories and vehicles were destroyed in the wildfires that have burned43,866 acres, the government’s emergency response center said.

In a televised address, South Korea’s acting President Han Duck-soo said the wildfires that began last Friday were worse than many previous ones.

“Damages are snowballing,” Han said.
