North Korea's propaganda attack on South Korea is intensifying by the day.

The North's Korean Central Television showed footage Thursday of citizens firing pistols at a paper target depicting the image of South Korean President Lee Myung-bak. The event was part of defense drills conducted by members of a women's organization under the Workers' Party and athletes of a sports team.

During interviews, they spoke angrily using vulgar language to denounce the South Korean president.

North Korea has taken issue with a South Korean military unit in Incheon for putting up a hostile slogan on the photos of North Korean leader Kim Jong-un and his late father Kim Jong-il.

Since the slogan was sighted last month, the North has escalated its slanderous rhetoric against Seoul.
