The head of a United Nations commission investigating abuses in Syria says violence has spread so vastly that the “civilian space is almost completely eroded.” Paulo Sérgio Pinheiro said the commission has been gathering evidence about 20 massacres that have taken place in Syria. Another commission member said both sides in the conflict between President Bashar al-Assad and anti-Assad rebels are committing war crimes, but that it seems government authorities are “involved more in regard to crimes against humanity.” The U.N. refugee agency has warned the number of refugees outside Syria could triple by the end of 2013 if the nearly two-year conflict is not resolved. The one millionth Syrian refugee was registered last week.
