A food market shows off rows upon rows of dead animals, some of which have been beaten to death. Dogs and chickens can be seen lined up with their mouths hanging wide open.

Retired biologist and amateur photographer Alf Jacob Nilsen took the shocking pictures of the market during a visit to Tomohon Village in Northern Sulawei, Indonesia. Pictured: Flying foxes (bats) for sale at the market. (Photo by Alf Jacob Nilsen/Solent News)
