Pyongyang, December 23 (KCNA) -- Four days have passed since Koreans were shocked to hear the news of the untimely passing away of leader Kim Jong Il.

People's sorrow over the loss of their leader grew throughout days.

Flow of mourners converged on Kim Il Sung Square where a huge portrait of smiling Kim Jong Il hangs.

Officials of the Ministry of Electronics Industry were interviewed by a reporter at the square.

Vice-minister Hwang Jong Sik, 61, said:

The great leader used to give valuable instructions to develop the national electronics industry.

We feel deeply regretful as Kim Jong Il died of heavy burden of work because we failed to work hard true to his lofty intentions.

We will make all our efforts and wisdom for the development of the electronics industry true to the leadership of Kim Jong Un as wished by Kim Jong Il.

O Jong Sun, 55, department director, said that history has never seen such a great man as Kim Jong Il who dedicated his all to the country and people standing hardships. We feel growing pangs of compunction of not having held him in higher esteem.

Kim Tok Chol, 44, head of shop at the Electronics Development Company, said:

Kim Jong Il promised us to come to see us, hearing that we have developed our own style laptop.

So we looked forward to seeing him at our worksite.

But we have received the sad news. How can we be told that we have fulfilled our obligation as his soldiers.

We feel deeply regretful.

We will overcome this sorrow and dedicate everything to the building of the thriving nation of Juche, his life-long desire, under the leadership of Kim Jong Un, vice-chairman of the Central Military Commission of the Workers' Party of Korea.
