The United States' top diplomat arrived in Ankara on Wednesday to discuss the case of missing Saudi dissident journalist Jamal Khashoggi, according to state news agency Anadolu.

Secretary of State Mike Pompeo was met by President Recep Tayyip Erdogan at the airport, Anadolu reported, without giving details. The US official is also scheduled to meet Turkish Foreign Minister Mevlut Cavusoglu.

Pompeo's visit comes a day after he met with the Saudi leadership in Riyadh to discuss Khashoggi's disappearance.

Khashoggi, a vocal critic of Saudi Arabia's powerful Crown Prince Mohammed bin Salman, was last seen at the Saudi consulate in Istanbul on October 2 where he had gone to pick up papers so he could marry a Turkish woman.

Turkish officials have told media that the 60-year-old journalist, who wrote a column for the Washington Post, was murdered inside the consulate. Saudi Arabia has denied the allegations.
