(CNN) -- New videos posted from the Syrian flashpoint city of Homs suggest a fresh wave of killings by the Syrian military after the fall of the neighborhood of Baba Amr. Activists have provided CNN with footage purportedly showing the bodies of 17 civilians that were discovered February 29 in villages near Baba Amr following an all-out assault on the Homs neighborhood that had held off a government assault for weeks. Much of the video is too graphic to show on air, but analysis of the video showed at least 12 bodies. In one, bodies are piled up in the back of a truck bed covered in blankets. Snow falls on the bodies as people in the background wail, some shouting, "There is no God but God!" One man off camera says, "These are the victims of the massacre by the Shabiha (a government militia), entire families slaughtered by the forces of Assad" -- a reference to Syrian President Bashar al-Assad.
