The Ministry of Unification here said that North Korea seeks to mislead South Koreans' sentiments and drive a wedge among them by releasing politically charged messages.

"It is nothing new that North Korea is trying to interfere in South Korean politics," Lee Duk-haeng, ministry spokesman, said at a regular press briefing. "North Korea should stop its anachronistic behavior."

Former President Park Geun-hye, a conservative, was removed from office last month when she was impeached following a corruption scandal involving her and her close friend.

Presidential front-runner Moon Jae-in of the liberal Democratic Party stayed slightly ahead of his biggest rival Ahn Cheol-soo of the center-left People's Party, according to the latest polls.

North Korea's propaganda website Uriminzokkiri said Tuesday that the conservative bloc is seeking to cast ballots for Ahn to prevent the liberal candidate Moon from assuming power. (Yonhap)
