North Korean dictator Kim Jong Un has reportedly criticised a turtle factory for “serious shortcomings” after it failed to breed lobsters.

The dictator toured the Taedonggang Terrapin Farm outside Pyongyang on Monday, according to a release from the state’s official media outlet.

Mr Kim, who allegedly executed his defence minister last week, appeared upset that farm officials had failed to successfully breed from the freshwater lobsters provided to the factory two years ago.

The official report labelled workers failings as a “manifestation of incompetence, outmoded way of thinking and irresponsible work style.”

He also said that workers had failed to pay proper respect to the country’s former leader and his father Kim Jong Il.

He noted employees “who failed to bear deep in their minds his leadership exploits could hardly perform their role as masters in production".
