The Attorney General of Saudi Arabia stated Thursday that the suspects in the murder of journalist Jamal Khashoggi acted with premeditation.

This information came to light from a joint effort between Saudi Arabia and Turkey. The prosecution stated that it will continue its investigation in light of this new information.

Khashoggi was last seen walking into the Saudi Arabian consulate in Istanbul on October 2. It is widely believed that his disappearance is a result of him publishing columns in the Washington Post that were critical of the Saudi Royal Family.

In his last Washington Post article before disappearing, Khashoggi was critical of the country’s actions with respect to its neighbor, Yemen. Khashoggi pointed out that the Kingdom has racked up $11 billion in debt from the conflict, partially from using expensive US-made missile systems. Additionally, he stated that the conflict with Yemen did not increase national security as it was supposed to; the conflict has instead “increased the likelihood of domestic casualties and damage.”

Due to the alleged murder happening inside the Saudi consulate, Turkey was unable to investigate until they had the consent of the head of the Saudi diplomatic mission. The UN Human Rights Chief urged last week for transparency in investigating this matter.

On Tuesday the US State Department announced it would revoke the visas for all those suspected to be responsible for Khashoggi’s murder. This list of 21 individuals includes people from the Saudi royal court, intelligence agencies and other government ministries.
