United Nations observers in Syria say they have found 13 bodies, bound and shot, in the east of the country.
That comes just days after the massacre of about 100 people in the town of Houla.
Many of those victims were children, shot at close range, or killed with knives.
About 10 countries, including the US, have expelled Syrian diplomats in protest over the massacre.
And the UN human rights council has scheduled an emergency meeting for Friday.
There's an urgent sense that the international community has to do something.
But there's no consensus on what.
Marco Werman finds out what's happening at the United Nations from Colum Lynch, UN correspondent for the Washington Post.
