Reconstruction work is underway in Ryongchon, the North Korean city leveled by a devastating train blast on April 22.
According to a South Korean relief worker who delivered emergency supplies to the victims on Friday, some 200 construction workers have begun building houses at the entrance of Ryongchon city.
The relief worker said that construction workers have begun to lay bricks about one meter above ground level for houses and that there were a number of heavy construction equipment as well as trucks for transportation.
