MOSCOW, October 30 (Itar-Tass) - Russia is deeply concerned over the reports on the use of chemical weapons by the extremists in north-eastern Syria, the Russian Foreign Ministry stated on Wednesday.

“This information certainly should be checked thoroughly and should be investigated. Meanwhile, we recall again that U.N. Security Council Resolution 2118 approved unanimously shoulders special responsibility on neighbouring countries to Syria in order to prevent the chemical weapons from falling in the hands of non-state elements,” the Russian Foreign Ministry stated.
