Mubarak Bin Said Ben Zaïr and Jihad Abdulkarim Al-Khodr, both sons of prominent Saudi human rights activists, were amongst those arrested during peaceful protests outside the Interior Ministry in Riyadh on 20 March 2011. Demonstrators were calling for the release of thousands of longstanding prisons held in Saudi prisons without charge or trial. The two men remain in custody despite not having been charged.
