A group of about 40 South Korean activists and North Korean defectors launched balloons over the border carrying leaflets criticising the anticipated power succession in their northern neighbour.

More than five million North Koreans have so far turned out to pay their respects to late leader Kim Jong-il, state media says.

The body of Mr Kim is lying in state in the capital Pyongyang as organised public mourning continues around the country.

The BBC's Lucy Williamson reports.
