US Secretary of State Mike Pompeo is expected to head to Turkey Wednesday following meetings with Saudi King Salman and his son, Crown Prince Muhammed bin Salman Al Saud, in Riyadh, the Turkish Foreign Ministry confirmed in a statement today. The ministry said he would be meeting with Turkish Foreign Minister Mevlut Cavusoglu to discuss regional and international matters but did not elaborate. The full details of his program have not yet been disclosed and US Embassy staff in Ankara declined to comment on the visit.

Pompeo’s trip to Ankara comes amid fresh details of the alleged murder of dissident Saudi journalist Jamal Khashoggi, who went missing after entering the Saudi Consulate in Istanbul Oct 2.

Pompeo will likely brief Turkish President Recep Tayyip Erdogan on his talks with Saudi leaders, part of an effort to resolve the crisis, which has drawn global ire.

Erdogan said Turkish officials who scoured the consulate premises for nine hours on Monday were looking into “toxic” and freshly painted material ostensibly altered to conceal traces of the alleged slaying of the Washington Post columnist, who was a vocal critic of the famously thin-skinned Saudi heir to the throne. “My hope is that we can reach conclusions that will give us a reasonable opinion as soon as possible because the investigation is looking into many things such as toxic materials and those materials being removed by painting over them,” Erdogan told reporters.
