Saudi Arabia has agreed to let Turkish authorities search the kingdom's Istanbul consulate after prominent journalist and Riyadh critic Jamal Khashoggi went missing last week, the Turkish foreign ministry said Tuesday.
The search will take place as part of the official investigation, which was being conducted "in an intense manner", he said without giving any date.
Khashoggi, a Washington Post contributor who wrote for Arab and Western media, vanished last Tuesday after visiting the consulate to obtain official documents.
Turkish police were looking into two private aircraft which landed at Istanbul's Ataturk airport on Tuesday at different times carrying 15 people of interest in the case, as well as the possibility that Khashoggi was kidnapped and taken aboard one of the planes, local media reported.
Previously Saudi Crown Prince Mohammed bin Salman told Bloomberg that Riyadh would be ready to welcome Turkish officials to search the premises.
Ankara sought permission Sunday to carry out a search after the foreign ministry summoned the Saudi ambassador for a second time, Turkish television reported.
Riyadh's envoy in Ankara was first called to the ministry on Wednesday.
Khashoggi, a former Saudi government adviser, had been living in self-imposed exile in the United States since last year fearing possible arrest.
He has been critical of some policies of the crown prince and Riyadh's intervention in the war in Yemen.
While Riyadh claimed he had left the consulate after his visit, Turkish police said Khashoggi did not emerge from the building.
Government sources said police believe the journalist was killed inside the consulate.
Police also said a team of 15 Saudis were sent to Istanbul and were in the building at the same time as Khashoggi.
Turkish security officials were working to identify the 15 individuals, English-language state broadcaster TRT World reported, adding that Turkish officials believe the Saudis may have taken the consulate's CCTV footage with them when they returned to Saudi Arabia.
According to pro-government daily Sabah, the team arrived in Istanbul on two private planes, one which landed after 03h00 (0000 GMT) on Tuesday while the second plane landed around 17h00 (1400 GMT) after Khashoggi entered the consulate.
The individuals checked into two hotels close to the consulate, the daily said. Both planes later returned to Riyadh with one stopping in Dubai and the other in Egypt, Sabah reported, adding the police were looking into the possibility that Khashoggi was kidnapped.
The planes belonged to a company based in Saudi Arabia which has links to the state.
Istanbul police experts were analysing vehicles which entered and left the consulate, some of which were then seen on camera last Tuesday at the consul-general's residence, 200 metres away, the daily said.
The newspaper also claimed that Turkish employees at the residence were "hastily" told to take a holiday on the day Khashoggi went missing.
