Secretary of State Mike Pompeo met with Saudi Foreign Minister al-Jubeir in Buenos Aires on the margins of the G20 Summit on Friday.

“Secretary and Foreign Minister discussed a range of regional and bilateral issues including the upcoming talks related to the Yemen conflict as well as the importance of making progress on the investigation into Jamal Khashoggi’s death,” the State Department said in a statement.

On October 2, The Washington Post contributor Jamal Khashoggi entered the Saudi Arabian consulate in Istanbul, Turkey, to validate documents, but had gone missing. It was argued that he was killed there for writing articles that criticize Riyadh. Saudi Arabia, however, had denied these accusations claiming that the journalist had disappeared after leaving the consulate. But subsequently, Riyadh confirmed that Khashoggi was killed at the consulate.
