Body parts belonging to murdered journalist Jamal Khashoggi have been found, according to two Sky sources.

The sources have told Sky News the Saudi dissident had been "cut up" and his face "disfigured".

One source also suggested the writer's remains were discovered in the garden of the Saudi consul general's Istanbul home - located around 500 metres away from the consulate.

It contradicts the explanation being made by Saudi officials that the body was rolled up in a carpet and handed to a local collaborator who was tasked with disposing of the evidence.

Theresa May's spokesman said reports of Mr Khashoggi's body parts being found were "deeply disturbing".

"The location of Mr Khashoggi's body is just one of the questions we need answers to and as such we await the full results of the Turkish investigation," he said.
