PYONGYANG, Sept. 11 (Xinhua) -- The Democratic People's Republic of Korea (DPRK) called on its people to engage in a rehabilitation campaign in wake of strong storms, the official news agency KCNA reported Sunday.

The ruling Workers' Party of Korea has made it a top priority to rebuild the disaster-hit cities and counties, in particular in North Hamgyong Province in the northeast, where tens of thousands of houses and public buildings collapsed and railways and roads were destroyed, said the KCNA.

The floods were caused by the strongest storms and heaviest downpour since 1945, it noted.

The ruling party will launch a 200-day campaign to help with disaster relief and post-flood reconstruction.

The heavy rains have left more than 60 people dead and 25 missing in the North Hamgyong Province, according to an earlier KCNA report.
