The Syrian government’s ambassador to the United Nations on Monday told reporters in New York that a cache of toxic chemicals, “enough to destroy a city” and presumably left by opposition forces, was discovered in northwestern Syria.
Ambassador Bashar Ja’afari said the cache included about 280 containers filled with various toxic substances, such as ethylene glycol, ethanolamine, diethanolamine and triethanolamine.
“This is enough to destroy a whole city, if not the whole country,” Ja’afari said, without mentioning the date when the discovery was made. “At the moment, an investigation is underway with regard to this batch of chemical weapons.”
All the substances mentioned by Ja’afari are indeed harmful for humans, but are extensively used in various industrial and consumer products. None of them is considered a chemical weapon.
