'I treated people who had their skin melted'

Abu Sabah knew he had witnessed something unusual. Sitting in November last year in a refugee camp in the grounds of Baghdad University, set up for the families who fled or were driven from Fallujah, this resident of the city's Jolan district told me how he had witnessed some of the battle's heaviest fighting.
"They used these weird bombs that put up smoke like a mushroom cloud," he said. He had seen "pieces of these bombs explode into large fires that continued to burn on the skin even after people dumped water on the burns".
As an unembedded journalist, I spent hours talking to residents forced out of the city. A doctor from Fallujah working in Saqlawiyah, on the outskirts of Fallujah, described treating victims during the siege "who had their skin melted".
