Three North Korean cargo planes flew to China and back on Monday, as the country battles an fast-spreading
outbreak of Covid-19, according to a South Korean government official with knowledge of the matter. The planes traveled to Taoxian International Airport in Shenyang, in China's northeast Liaoning province, the official said. It's unknown what the planes were carrying, but the rare trip came after China pledged to help
North Korea with its Covid outbreak, which experts have warned could cause a major humanitarian crisis in the isolated and impoverished nation.
