RIYADH, Saudi Arabia (AFP) — Saudi Arabia dismissed on Saturday accusations that Jamal Khashoggi was ordered murdered by a hit squad inside its Istanbul consulate as “lies and baseless allegations”, as Riyadh and Ankara spar over the missing journalist’s fate.

As the controversy intensified, the Washington Post reported Turkish officials had recordings made from inside the building that allegedly proved their claims Khashoggi was tortured and killed at the consulate.

A Saudi delegation arrived in Turkey for talks, officials said on Friday, with the case risking fragile relations between the two.

In the first Saudi ministerial reaction to the accusations about Khashoggi’s killing, Interior Minister Prince Abdel Aziz bin Saud bin Nayef said that “what has been circulating about orders to kill him are lies and baseless allegations”.

The Kingdom “is committed to its principles, rules and traditions and is in compliance with international laws and conventions”, he added according to the official Saudi Press Agency.

The case risks damaging the image of the kingdom and its ties to the West as Crown Prince Mohammed bin Salman promotes a reform drive at home.

Big names from media and business have already cancelled appearances at a major conference in Riyadh this month.

Saudi journalist and Washington Post contributor Khashoggi vanished on October 2 after entering the consulate to obtain documents for his upcoming marriage.

Turkish government sources say police believe he was killed but Riyadh denies that.

The Saudi delegation, whose composition was not immediately clear, is expected to meet with Turkish officials in Ankara at the weekend, state media said on Friday.

It is likely that they will take part in a joint working group on the case, whose creation was announced Thursday by Turkish presidential spokesman Ibrahim Kalin following a request by Saudi Arabia.

A Saudi official source quoted by SPA news agency said it was “a positive move” Turkey had agreed to the creation of what it described as a “joint action team” over Khashoggi’s disappearance.

The Turkish leadership has so far stopped short of accusing Saudi Arabia, although pro-government media have published sensational claims, including that an “assassination team” was sent to Istanbul to kill Khashoggi.
