A report on Jamal Khashoggi’s assassination published last week by the UN special rapporteur on extrajudicial killings, Agnes Callamard, said the murder was premeditated and that the state of Saudi Arabia was responsible under international human rights law.

This week, she presented the report to the UN human rights council as the Saudi crown prince, Mohammed bin Salman – the man she believes liable for the murder – flew to Japan for a G20 summit.

The Guardian’s head of investigations, Nick Hopkins, and its US investigations correspondent, Stephanie Kirchgaessner, discuss the findings and the political reaction, and reveal they have been warned they could be targets of Saudi government hackers.
