North Korea's Kim Jong-un makes another appearance with walking stick Rodong Sinmun/KCNA

North Korean leader Kim Jong-un, who was not seen in public for a long time, has made a second appearance with a walking stick.

The 30-something leader was seen leaning on a cane during a field visit to a residential complex.

The state-run Korean Central News Agency (KCNA) has released several pictures of the leader as he was touring the facility given to scientists and teachers.

The KCNA report read: "Watching with satisfaction the twin 46-storyed apartment houses, he noted with pleasure that they look like sailing ships on the River Taedong and they are attractive as their outer walls are covered with heat ray reflection glass."

Several related photographs were also carried by the North Korean ruling Communist Party mouthpiece Rodong Sinmun.

The latest pictures are widely seen as Pyongyang's attempt to quell speculation, which arose during Kim's 40-day absence, over political stability in the isolated country.

Kim is believed to have undergone knee or ankle surgery recently forcing him away from public in the past few weeks.
