I got a message on Sunday that the Tahrir Square field hospital needed medical help and supplies. As I used to be a nurse, I went. The tear gas is toxic in a way it was not in January. Various people have said that the cyanide component is greater or that phosphorus is causing the problem. I can positively confirm that the gas injuries are completely different and much more severe. We treated hundreds of youngsters who had totally collapsed and were not breathing. Most came to quickly but we had two deaths and one, a young boy, asphyxiated. This evening, every gas victim has come in twitching or seriously fitting. Some gas wafted into the mosque. You couldn't see it but immediately my eyes began to stream and my skin started to burn. In the January Revolution, I saw the gas coming and the effects irritated my eyes, nose and throat. The eye irritation was intense but this is different. I never had a sense of my skin burning in January even with close range exposure.
