North Korean leader Kim Jong Un has ordered at least two people executed, banned fishing at sea and locked down the capital, Pyongyang, as part of efforts to guard against the coronavirus and its economic damage, South Korea’s spy agency told lawmakers Friday, AP reported

Kim’s government also ordered diplomats overseas to refrain from any acts that could provoke the United States because it is worried about President-elect Joe Biden’s expected new approach toward North Korea, lawmakers told reporters after attending a private briefing by the National Intelligence Service (NIS).

One of the lawmakers, Ha Tae-keung, quoted the NIS as saying Kim is displaying “excessive anger” and taking “irrational measures” over the pandemic and its economic impact.

Ha said the NIS told lawmakers that North Korea executed a high-profile money changer in Pyongyang last month after holding the person responsible for a falling exchange rate. He quoted the NIS as saying that North Korea also executed a key official in August for violating government regulations restricting goods brought from abroad.

North Korea has also banned fishing and salt production at sea to prevent seawater from being infected with the virus, the NIS told lawmakers.
