Saudi Arabian Crown Prince Mohammed bin Salman arrived in Argentine for G20, a visit fraught with controversy over the killing of Saudi journalist Jamal Khashoggi.
Human Rights Watch asked Argentina on Monday to use a war crimes clause in its constitution to investigate any involvement by the crown prince in possible crimes against humanity in Yemen and Khashoggi’s murder.
Western nations are also calling for an end to the Saudi-led military campaign in neighboring Yemen, which was launched by Prince Mohammed, as a humanitarian crisis there worsens.
The G20 leaders’ summit begins on Friday.
