North Korea is suffering from serious droughts that have led to a sharp drop in grain production and the drying of many rivers, a U.S. charity group said in a report after a trip to the impoverished communist nation.

Christian Friends of Korea (CFK), a U.S.-based nonprofit organization, sent an 11-member team to North Korea from March 18-April 8 to check on the distribution of its assistance and treat hepatitis patients in medical care centers across the country.

The organization posted a report on its website detailing the team's trip.

"Throughout our travels, we heard from many care centers that the 2018 corn crop sustained heavy losses (40-50 percent reduction) due to the drought and prolonged high temperatures last summer," the report said.
