Turkish Foreign Minister Mouloud Gawishoglu said his country would not hesitate to resort to international investigation if the case of the killing of Saudi journalist Jamal Khashoggi has reached a dead end.

"We will continue to the end, and we will not hesitate to resort to international investigation if there is a deadlock in the course of the case," the Turkish minister told a news conference in Brussels on Wednesday.

"He did not come from the street, so his name and contact information are in Saudi Arabia," Oglu told the local collaborator in one of the Saudi accounts of the crime, adding that Saudi Arabia should inform us of the information it received in the Khashoggi investigation.

In a related context, renewed UN High Commissioner for Human Rights Michelle Bachelet demand for an international investigation into the case of Khashoggi's killing, and said that the international investigation needs to request a Member State of the Security Council, which is necessary to identify those responsible for the operation described by the ugly, in a speech in A press conference in Geneva marking the 70th anniversary of the Universal Declaration of Human Rights.

Earlier in the day, the Turkish prosecutor issued an arrest warrant for former deputy intelligence chief Ahmad Asiri and Saudi Crown Prince Saud al-Qahtani for Khashoggi's murder.

The Istanbul prosecutor's office said he believed there was "strong suspicion" that Asiri and al-Qahtani had participated in planning Khashoggi's murder at his consulate in Istanbul, adding that their charges were murder with brutal torture and pre-planning.

After evaluating the request, the Turkish Penal Court decided to issue an arrest warrant against Asiri and Al-Qahtani.

Commenting on the matter, a Turkish official said the prosecution's move reflected his conviction that Riyadh would not take any formal action against Asiri and al-Qahtani, calling on Saudi Arabia to allay international fears by handing over all the suspects in Khashoggi's death to Turkey.

The official added that Riyadh did not provide answers to questions regarding the fate of Khashoggi's body and who issued the order of murder.
