Visitors walk on a walking track in Belgrad Forest on an autumn day in Istanbul, Turkey
Police in Turkey investigating the alleged killing of Saudi journalist Jamal Khashoggi have expanded their search.

Unnamed Turkish officials say his body may have been disposed of in the nearby Belgrad forest or on farmland.

Mr Khashoggi disappeared after entering the Saudi consulate in Istanbul on 2 October, where Turkish officials allege he was murdered.

Saudi Arabia denies any knowledge of what happened to him.
Samples taken from the Saudi consulate and the consul's residence during searches this week are being tested for a match with Mr Khashoggi's DNA.

The BBC understands the police are searching the Belgrade forest because it is believed at least two vehicles from the Saudi consulate headed in that direction on the day of the suspected killing.
Meanwhile, 15 Turkish nationals employed at the Saudi consulate in Istanbul have been questioned by prosecutors, state news agency Anadolu reports.

Those giving witness statements included receptionists, technicians, accountants and a driver, Anadolu said.
