North Korea’s state media has confirmed that several North Koreans were killed or injured while working in freezing cold weather on the construction site of a power plant.

The North’s Rodong Sinmun said in an article on Wednesday that some members of the youth group called the Paektusan Hero Youth Stormers suffered severe frostbite as they walked hundreds of kilometers carrying construction materials. It said that a female nurse died as she tried to stop equipment from slipping at the construction site.

The report mentioned all the names of the victims who were killed while working at the construction site of the Paektusan Hero Youth Power Station near the border with China.

It said that North Korean leader Kim Jong-un, who visited the site in September last year, expressed his deep respect for the patriotism of the young people working in the harsh weather conditions.

Kim made two visits to the site in April and September last year to encourage the workers.
