Pyongyang, November 23 (KCNA) -- The House of Class Education in Kaesong City, DPRK has displayed over 150 pieces of new materials testifying to the Japanese imperialists' crimes against the Korean people.

The new exhibits include iron stakes which had been driven on rocks of Mt. Songak and other mountains in the city by the Japanese imperialists during their colonial rule over Korea to kill the soul of the Korean nation, as well as photos showing their crime.
