South Korea has delivered relief supplies for victims of last month's train disaster in the North via a cross-border land route.

The relief convoy of cargo trucks left Munsan in the South, Friday morning and arrived in the North's Gaesong City, where North Korean authorities took over for delivery to Ryongchon, the site of the devastating rail blast.

The relief package, worth some one billion won, is mostly comprised of 50 blackboards and 1,500 sets of desks, chairs and other supplies needed for rebuilding schools that were destroyed in the train explosion.

South Korea will also donate the 20 trucks that transported the relief materials to the North to be used in its reconstruction and restoration efforts.

The latest delivery is South Korea's fifth shipment of relief supplies for victims of the Ryongchon accident.
