BEIRUT, Nov 6, (AFP): Activists accused the Islamic State (IS) group Friday of being behind a deadly gas attack in northern Syria this past summer, as the global chemical weapons watchdog confirmed it was mustard gas. Meanwhile, Islamist rebels wrested back a flashpoint town in the central province of Hama, reversing the last of gains the army had made in a month-old offensive. The Organisation for the Prohibition of Chemical Weapons on Friday confirmed with “utmost confidence” that mustard gas was used in August in Syria.
A report from OPCW fact-finding teams said an infant was “very likely” killed in the attack on Marea, a town in Aleppo province, on August 21. OPCW said the mustard gas was used by non-state actors, but activists and a monitoring group said it was clear that IS was behind the attack. Rami Abdel Rahman, head of the Syrian Observatory for Human Rights monitoring group, said “IS used toxic gases during its attack on Marea in August.” He said IS had likely gotten the gas through Turkey or Iraq. Journalist Maamun al-Khatib, who was in Marea at the time, said: “We knew it was IS because all the shells were being fired east of Marea, and that area is totally under the control of IS.” IS has attacked Marea for months in an effort to cut off a supply route into the country from Turkey.
For activist Nizar al-Khatib, OPCW’s report “comes too late and isn’t enough, because it doesn’t identify IS as the one responsible for firing the mustard gas.” Doctors Without Borders (MSF), which operated a nearby field clinic, treated four members of a single family for “symptoms of exposure to chemical agents.” The Marea residents told MSF they saw a “yellow gas” when a mortar round hit their house. An MSF spokesman said Friday that the Paris-based group did not have enough evidence to finger IS. The OPCW report also said toxic chemicals, including chlorine, were used in an attack in March in the northwest province of Idlib. Six people, including three young children, were killed in an apparent chlorine attack in the village of Sarmin in Idlib province on March 17, the Observatory and activists said. After a chemical attack that killed hundreds in the Eastern Ghouta region east of Damascus in August 2013, Syria agreed to declare and hand over its chemical weapons in a deal overseen by OPCW.
Meanwhile, Islamist fighters including Ahrar al-Sham seized a town in Hama province, rolling back a series of recent gains by the beleaguered armed forces of Damascus. Ahrar al-Sham and allied rebels overran Atshan and nearby villages in the morning and, despite Russian air support, the army was unable to push them back, the Observatory said. Russian warplanes had been key to the army’s gains in the offensive it launched in Hama on October 7, one of several ground assaults across Syria backed by Moscow. The government captured Atshan on October 10, but withdrew from it and nearby towns, including Umm al- Haratayn, on Friday. “Regime forces lost control of the last remaining towns it had seized since the beginning of its ground operations in the northern parts of Hama province,” Observatory chief Rami Abdel Rahman said.
