Saudi Arabian authorities changed their account Thursday of how journalist Jamal Khashoggi was killed, for the first time calling his death a “premeditated” murder.

Public prosecutor Saud al-Mojeb said in a statement that the conclusion was reached by Saudi investigators after reviewing evidence given to them by Turkey.

The Saudi government initially said Khashoggi was killed in a “brawl” and a fistfight that escalated inside the Saudi consulate in Istanbul. Turkish officials have said they have evidence Khashoggi’s murder was a brutal, premeditated operation.
