Saudi Arabia's foreign minister has ruled out the extradition of suspects in the murder of journalist Jamal Khashoggi, after Istanbul's chief prosecutor filed warrants for the arrest of two former senior Saudi officials.

Turkish officials said last week that the prosecutor's office had concluded there was "strong suspicion" that Saudal-Qahtani, a top aide to Crown Prince Mohammed bin Salman, and General Ahmed al-Asiri, who served as deputy head of foreign intelligence, were among the planners of Mr Khashoggi's murder at the Saudi consulate in Istanbul.

"We don't extradite our citizens," Saudi Foreign Minister Adel al-Jubeir said when asked about the arrest warrants.

He was speaking at a news conference at a Gulf Arab summit in Riyadh.

"The Turkish authorities have not been as forthcoming as we believe they should have been," said Mr Jubeir, saying Riyadh was presented with information that had already been leaked to the media.

"We have asked our friends in Turkey to provide us with evidence that we can use in a court of law. We have not received it in the manner that it should have been received."

Last month, the US Treasury sanctioned 17 Saudis, including Mr Qahtani but not Mr Asiri, for their role in Mr Khashoggi's murder.

The Saudi public prosecutor has said the order to repatriate Mr Khashoggi came from Mr Asiri and that a travel ban has been imposed on Mr Qahtani.

Mr Jubeir declined to confirm or deny whether the men were currently detained, referring the question to the Saudi public prosecutor
