On October 19, the US State Department finally admitted that the rebels associated with the Fateh al-Sham (formerly known as al-Nusra Front) and Daesh had used chemical weapons in Syria.

Axar.az reports citing Sputnik that, the US-led coalition against the Daesh terrorist organization does not comment on the reports by the Syrian army regarding their findings of chemical weapons in the Syrian city of Deir ez-Zor, a press office of the Combined Joint Task Force — Operation Inherent Resolve (CJTF-OIR) told on Monday.

The CJTF-OIR added that Daesh terrorists have used "a wide range of barbaric tactics over the past two years, including use of civilians as human shields, use of chemical weapons, use of non-combatant citizens' homes to use as fighting positions, occupying schools and using them as weapons storage facilities, and converting mosques and hospitals into military bases for terrorist operations."

"We are working with our Coalition partners to defeat Daesh and prevent them from repeating these egregious violations of the Law of Armed Conflict," the press office stated.

A Sputnik correspondent reported on Sunday that the Syrian army had found a car packed with explosives, including chemical substances in Deir ez-Zor. One of the explosives was marked with an inscription that it contained chemical elements, which can only be used in laboratories.

The Syrian Armed Forces General Staff announced that Deir ez-Zor was completely liberated from Daesh.
