TURKISH media have released images of the 15-member “assassination squad” believed by the country’s police to have been deployed to murder Saudi journalist Jamal Khashoggi.

Turkish investigators believe Mr Khashoggi, who has not been seen since entering the Saudi consulate in Istanbul on October 2, was murdered there, probably because of articles he has written critical of Saudi Crown Prince Mohammed bin Salman.

Video also shows a black van leaving the consulate and travelling to the residence of the consul, which could have been a means of removing Mr Khashoggi’s body. The Saudis have said accusations that the journalist was killed on their orders are “baseless” and say they will allow Turkey to search their consulate, although a date for such a search has not been specified.

Public-sector broadcaster TRT released video showing Saudi citizens arriving by private jet and then leaving a hotel, and a black van with diplomatic licence plates driving to the consul’s home and parking in a garage. The van appears to be one pictured outside the consulate when Mr Khashoggi was caught on CCTV entering it.

Turkish newspapers say the members of the so-called “assassination squad” checked into Istanbul hotels and left them on October 2.

Mr Khashoggi’s Turkish fiancee has appealed to Saudi King Salman and the crown prince to release all CCTV footage taken at the consulate that day, and to US President Donald Trump to use his influence with the Gulf monarchy, a close ally of the US and Britain, to get them to come clean.
