Turkey said on Tuesday that it will search the Saudi Arabian consulate in Istanbul for Jamal Khashoggi as a photo emerged of the missing journalist walking into the building just hours before he suddenly vanished.

Turkish officials believe the Saudi government critic was killed inside the consulate and his body removed in a convoy of diplomatic vehicles.

A surveillance photo showing Khashoggi entering the Saudi compound and published by The Washington Post — for which he was a contributor — was apparently his last known sighting.

Amid growing tensions between the two nations over the incident, a spokesman for Turkey’s Foreign Ministry said Saudi officials are “open to cooperation” and would allow the consulate to be searched. But the ministry did not provide a timeline for when that might happen.

The surveillance image, which the newspaper said it received from a “person close to the investigation,” includes an Oct. 2 time stamp of Khashoggi, 59, walking to the consulate’s main entrance.

His fiancée said he went inside to get paperwork so he could remarry — but never emerged.

Hatice Cengiz, 36, told the Washington Post that she called the consulate about three hours later trying to find out where he was. A man eventually came to the entrance and told her, “There’s no one inside.”

Saudi officials insist Khashoggi left the consulate on his own.

President Trump on Tuesday said he had not yet talked to Saudi Arabia — a US ally — about the matter, “but I will be at some point.”

Turkish officials are poring over flight records and scrutinizing surveillance video to track the movements of 15 Saudi nationals who landed in Istanbul in two Gulfstream jets belonging to a Riyadh-based company the same day Khashoggi disappeared, the Turkish newspaper Sabah reported.

The group in the first plane headed to two hotels near the consulate and checked in. But the team in the second plane headed directly to the consulate.

Six vehicles were then seen leaving the consultant two-and-a-half hours after Khashoggi stepped inside.

“There were 15 Saudi officials and intelligence workers in the vehicles, the Turkish paper reported. “A Mercedes Vito with tinted windows and another vehicle went to Consul-General’s Mohammad al-Otaibi’s residence 200 meters away” and stayed for four hours.

Turkish employees at Otaibi’s residence were “hastily” told to leave that day.

Both planes left Istanbul that evening. One stopped in the United Arab Emirates and the other stopped overnight in Egypt, according to the report.

The newspaper added that investigators were examining security cameras near the hotels, tracking the movements of the vehicles and also looking into the possibility that Khashoggi was abducted with the help of another country’s security services.
