The first allegation of chemical weapons use was reported. Seven people were allegedly killed in Homs by a “poisonous gas” used by the Assad regime. The coverage included the report of side effects such as nausea, relaxed muscles, blurred vision, and breathing difficulties.

He said field doctors in Homs were seeing patients “losing consciousness, experiencing severe shortness of breath and vomiting.”
