A 34-year-old Russian has been charged with cutting up and roasting parts of his baby niece in an oven, police said on Thursday.

Police said the man, who has just two fingers, killed the two-year-old girl after a drinking session with the child's mother - his sister - in a village in the Oldonda Borzinsky district of Russia's Transbaikal region.

The child was killed while the mother was briefly visiting neighbours, police said.

When she returned, she was unable to locate her child, which was subsequently discovered dead in the oven.

Body parts believed to have belonged to the child were also discovered in the kitchen.

Police said the suspect had appeared "indifferent" to goings-on before and after his arrest.
