The Yemeni government said in a statement the findings of the Saudi probe "reflect the continuous and serious follow-up by the Saudi institutions," according to the official Saba news agency.
The statement said Riyadh "has always reviewed any mistake that may occur from one of its institutions and work to address it immediately and take the necessary actions and bring perpetrators to accountability as what happened in this incident [the killing of Khashoggi]."

Abdullatif bin Rashid Al Zayani, the Secretary-General of the Gulf Cooperation Council, for his part, described the Saudi measures as "firm" and "reflected the commitment of the Kingdom`s leadership to clarify the facts to the world public opinion."
On the day of Khashoggi`s disappearance, 15 other Saudis, including several officials, arrived in Istanbul on two planes and visited the consulate while he was still inside, according to Turkish police sources. All of the identified individuals have since left Turkey.
A joint Turkish-Saudi team completed an investigation into the case on Thursday after searching the residence of the consul general as well as the Saudi Consulate in Istanbul.
