"The European Union, like its partners, insists on the need for continued thorough, credible and transparent investigation, shedding proper clarity on the circumstances of the killing and ensuring full accountability of all those responsible for it. The memory of Jamal Khashoggi, the family of the journalist as well as his friends deserve justice," Mogherini said in a Saturday declaration, as quoted by the EU Council.
Mogherini expressed condolences to Khashoggi's family and friends as well as paid tribute to the memory of the murdered journalist.
"The emerging circumstances of Jamal Khashoggi's death are deeply troubling, including the shocking violation of the 1963 Vienna Convention on Consular Relations and particularly its Article 55," the EU foreign policy chief added.
The authorities said 18 Saudi nationals had been detained in relation with the matter, and intelligence chief Ahmad Assiri and senior aide to the Saudi crown prince Saud al-Qahtani had been sacked over the incident.
