[JURIST] UN High Commissioner for Human Rights Navi Pillay [official profile] on Thursday warned [press release] Syrian opposition groups that recent mass executions are in violation of international human rights, and that these acts may also constitute war crimes. Pillay claimed that she has received numerous reports from reliable eyewitness sources claiming that several civilians in the custody of armed opposition forces have already been executed this year. She reminded all parties involved that such executions are clearly prohibited by Common Article 3 of the Geneva Conventions [text], which states that those taking no part in hostilities are to be treated humanely. Calling the reports "deeply disturbing," Pillay urged all parties "to strictly respect their obligations under international law and remind[ed] them that everyone involved in serious crimes must be held accountable."
