it for yourself. you say it was a massacre, yes? >> reporter: i mean, it's absolutely shocking to think i was there four days ago, the international community had four days to try and help those people. ben wedeman is absolutely right, certainly in zawiya there was no coordinated army response from the rebels. the number of defections were in ones and twos, when i asked how many people defected yesterday, they would say rather proudly, we had one, we had two. we have actual film evidence of ambulances being fired on, of a hospital being attacked, of young children, a 10-year-old boy amongst them being fired on. they are even attacking the mosques, the most sacred of places. this was whole scale killing of civilians, doctor after doctor, nurse after nurse told us, and we could see it for ourselves,
