This is one of several videos appearing on YouTube of atrocities in Syria. This one is allegedly a mass grave full of victims of government violence, which has reportedly resulted in 1,000 civilian deaths. Reports say the grave was near the southern Syrian city of Deraa and contained at least 13 bodies which were were discovered on Monday, May 16. Syrian authorities have barred media coverage of the uprising there, so it is hard to verify.
Add in this footage I previously posted on apparent atrocities as they occur on the streets and then go have a stiff drink.
