People in North Korea have told the BBC food is so scarce their neighbours have starved to death.
Exclusive interviews gathered inside the world's most isolated state suggest the situation is the worst it has been since the 1990s, experts say.
The government sealed its borders in 2020, cutting off vital supplies. It has also tightened control over people's lives, our interviewees say.
Pyongyang told the BBC it has always prioritised its citizens' interests.
The BBC has secretly interviewed three ordinary people in North Korea, with the help of the organisation Daily NK which operates a network of sources in the country. They told us that since the border closure, they are afraid they will either starve to death or be executed for flouting the rules. It is extremely rare to hear from people living in North Korea.
The interviews reveal a "devastating tragedy is unfolding" in the country, said Sokeel Park from Liberty in North Korea (LiNK), which supports North Korean escapees.
One woman living in the capital Pyongyang told us she knew a family of three who had starved to death at home. "We knocked on their door to give them water, but nobody answered," Ji Yeon said. When the authorities went inside, they found them dead, she said. Ji Yeon's name has been changed to protect her, along with those of the others we interviewed.
