Saudi Arabia's Dissenting Princes Are Being Hunted
Saudi Arabia - a key ally of the UK and America - has been ruled as an absolute monarchy since its foundation. Any opposition in the country is often brutally oppressed. BBC Arabic has been investigating allegations the Saudi monarchy has operated a system of illegal abduction and capture of dissident princes who have criticised the government, including evidence of princes kidnapped in Europe and forced back to Saudi Arabia, where they've not been heard from since.
