The United Nations Commissioner of Human Rights have called Sri Lanka and the Tamil Tigers to be investigated and prosecuted for ‘crimes against humanity’ and targeted sanctions against officials.

Members could refer Sri Lanka to the International Criminal Court or pursue their own investigations, Human Rights Chief Michelle Bachelet has said in a report.
 
A previous report found “credible evidence that both Sri Lankan security forces and LTTE were responsible for war crimes and crimes against humanity,” she said.
