Fisk is the first western journalist to reach the area and speak to people there. One is a senior doctor at the clinic that treated victims of what a video purported to show were chemical weapons used by the Syrian government.
That doctor says the video was real, but did not show the effects of a chemical weapons attack. It showed something else. This is what the doctor is reported saying:
I was with my family in the basement of my home three hundred metres from here on the night but all the doctors know what happened. There was a lot of shelling [by government forces] and aircraft were always over Douma at night — but on this night, there was wind and huge dust clouds began to come into the basements and cellars where people lived. People began to arrive here suffering from hypoxia, oxygen loss. Then someone at the door, a 'White Helmet', shouted 'Gas!", and a panic began.
