WASHINGTON (Sputnik) — On Wednesday, Russian Center for Syrian Reconciliation commander Lt. Gen. Sergei Chvarkov stated that the opposition group Harakat Nour al-Din al-Zenki used poisonous gas in Aleppo city on August 2.
"[We] are looking into these allegations as well as the allegations of chlorine gas that was used by the regime in the town of Saraqib," Toner told reporters. "We would call on the OPCW [Organization for the Prohibition of Chemical Weapons] as well as the UN to use existing mechanisms to investigate these allegations thoroughly."
According to media reports, dozens of people were affected by toxic gas dropped in the Idlib province city of Saraqib on Monday.
Toner also noted that Moscow had alerted Washington of the second report, explaining that he was unaware of the briefing when asked on Wednesday.
On January 4, the OPCW announced that all chemical weapons in Syria that had been declared by Damascus had been destroyed. In April, reports emerged that Daesh militants could be using and producing chemical weapons in the country.
