Damascus, April 5 (IANS) Islamic State (IS) militants on Tuesday fired several shells containing mustard gas against Syrian military positions in the province of Deir al-Zour.
The poisonous gas shells slammed military positions in the vicinity of the Deir al-Zour air base, Xinhua reported.
Meanwhile, pan-Arab al-Mayadeen TV said several soldiers have suffered suffocation as a result of the gas attack.
The assault came as part of the terror group’s repetitive attempts to storm the Deir al-Zour air base, one of the last few military positions left under the Syrian government control in that oil-rich province near Iraq.
SANA on Monday said that Syrian forces foiled a large-scale IS offensive on the base.
