TOKYO, Sept 22 (Reuters) - Torrential rains and a typhoon have swept across North Korea, killing many people, triggering landslides and destroying tens of thousands of homes, the official Korean Central News Agency said on Friday.

The storms this month destroyed or damaged some 125,000 homes, of which 29,000 were completely demolished or swept away, with the damage estimated at more than $6.0 billion, the state news agency said.

Many people were killed or injured, it said, but gave no figures.

"A regional torrential rain and typhoon in September in particular claimed human lives and inflicted enormous disasters upon different sectors," it said.

The rains severed roads and railway communications, destroyed 1,930 bridges and cut off traffic for many days, said KCNA, monitored in Tokyo.
