Residents in Stockholm are divided over reports that rabbits are being used to make biofuel.

The bodies of thousands of rabbits are fuelling a heating plant in central Sweden, local newspapers say.

The city of Stockholm has an annual cull of thousands of rabbits to protect the capital's parks and green spaces.

The rabbits, not native to Sweden, are mainly the offspring of pets released by owners, and are said to be destroying parks in the capital.

Since they have no natural predators, the city administration of Stockholm employs hunters to kill the rabbits.
