Governments bear the primary responsibility for the protection of civilians and for ensuring accountability for conflict-related criminal offenses. In resolution 2122 (2013), adopted today, the Security Council once again calls on Member States to comply with their relevant obligations to end impunity and to thoroughly investigate and prosecute persons responsible for genocide, war crimes, crimes against humanity and other serious violations of international humanitarian law. At the same time, when national authorities fail to take action, the international community should play a more proactive role in ensuring an appropriate response. Such measures and appropriate protection and accountability efforts must obviously be free of selectively and politically motivated approaches and preferences. It is essential to address conflict-related violations and abuses of human rights through all available means, including, inter alia, by mandating international commissions of inquiry and fact-finding missions, as well as by supporting the implementation of the recommendations of those bodies and missions.
