Syrian mourners, one carrying the pre-Baath national flag adopted by the rebel movement, carry the body of a youth reportedly killed in violence in the northwestern Idlib region before his burial.

A United Nations human rights report released Thursday accused the Syrian government of crimes against humanity.

More than 5,000 people have been killed, and many were unarmed civilians. And while the panel accuses the Syrian opposition of some humanitarian crimes, it says most were committed and authorized by the highest levels of Syrian government.

Tomorrow, there will be an international meeting expected to gather more than 70 nations and groups in Tunisia to plan a response.
