Professor Paul McMaster:

What we try to do is provide the very best care we can for those in the most unstable condition and who are most vulnerable. It is frequently the case in warfare that there are rumours and accusations. I have experienced this in Sri Lanka, Somalia and Afghanistan. It is often stated truth is the first casualty of war. When I was in the field, I heard concerns being expressed. Médecins Sans Frontières' role is to look carefully at the condition and injuries of our patients. Should we see a pattern which gives rise to concern, we would be anxious to raise the matter with the appropriate authorities. My medical colleagues who are operating on the ground in Syria have seen no evidence of weapons that fall outside the normally accepted conventions. The Senator used another term to describe them.
