The accident occurred in North Hwanghae province, the foreign ministry said.
TEHRAN, Young Journalists Club (YJC) - The province lies south of the capital and stretches to the border with the South, including the city of Kaesong, an ancient Korean capital with historical sites.
The tour group was travelling by bus from Kaesong to Pyongyang when the accident happened, according to the independent Seoul-based website NK News, which cited an unnamed source.
State broadcaster CCTV showed images of a large overturned vehicle with light rain falling on rescue vehicles and doctors attending to a patient in its news broadcast of the incident.
