Winter Olympics: Friendly North Korea 'is fake', says former bomber

This year's Winter Olympics in South Korea has seen friendly overtures from the North, but Kim Hyun-hui is not convinced.

The former North Korean spy killed 115 people when she planted a bomb on a South Korean plane in the lead-up to the 1988 Summer Olympics in Seoul.

She tells the BBC's Laura Bicker what she thinks of the North's sincerity.
