North Korean leader Kim Jong Un's sister, Kim Yo Jong, has criticized South Korean President Moon Jae-in for his remarks about the North's missile launches last week.
In a statement carried by the Korean Central News Agency on Tuesday, Kim referred to a speech made by Moon last week.
In the speech, Moon called the recent ballistic missile launches by the North "undesirable" amid efforts to resume dialogue with Pyongyang.
Kim said it makes no sense for Moon to criticize the North's "self-defense" missile test. She noted that South Korea is itself conducting missile tests.
Kim slammed him, saying, "Such illogical and brazen-faced behavior of South Korea is exactly the same as the gangster-like logic" of the United States.
Kim's current official job title, according to the KCNA statement, is vice-director of the Information and Publicity Department of the Central Committee of the ruling Workers' Party.
