Airstrikes continued Tuesday. The opposition's Syrian Civil Defense search-and-rescue group reported at least nine people were killed in airstrikes on the town of Jisreen. The group, also known as the White Helmets, said two of its volunteers, and 28 others, suffered difficulties breathing following shelling on the town of Hammouriyeh on Monday evening. It accused the government of using "poison gas." The Observatory reported 18 people suffered breathing difficulties, without attributing a cause.
