United Nations human rights chief Navi Pillay is calling for an independent investigation into war crimes allegedly committed by Syrian rebel fighters.
Pillay said Friday that a U.N. team in Syria found evidence that rebels executed at least 30 people last month in Aleppo. Most of the victims were Syrian soldiers. She said the killings were captured on video, calling the incident "deeply shocking."
Pillay said those on both sides of the war who break international humanitarian and human rights law need to be held accountable. She said rebel forces should not think they are immune from prosecution.
The U.N. says more than two years of civil war in Syria has killed more than 100,000 people and driven about 6 million from their homes. Most of the victims have been civilians.
