GENEVA (AP) — The violence in Syria has worsened since a cease-fire deal in April and the bloodshed appears to be taking on dangerous sectarian overtones, the U.N. said Wednesday.

Investigators say they have concluded that Syrian government troops could be behind the killing of more than 100 civilians in the village of Houla last month. The findings, which were presented to the U.N.’s top human rights body, could lay some of the groundwork for prosecuting alleged crimes against humanity and other abuses in Syria.
