International watchdog has confirmed the Islamic State has used mustard gas in a Syrian town where it was battling another group.
At least two people were exposed to sulphur mustard on August 21 in the town of Marea, north of Aleppo, writes a confidential report by Organization for the Prohibition of Chemical Weapons (OPCW) dated October 29.
The report said the effects of mustard gas may have also resulted with death of a baby.
However, the report has not yet mentioned whether the Islamic State used the mustard gas as claimed by diplomatic sources raising questions from where the sulphur mustard came from.
One source said, “Either they (IS) gained the ability to make it themselves, or it may have come from an undeclared stockpile overtaken by IS. Both are worrying options.”
About one-and-half years ago Syria is believed to have surrendered its toxic chemicals as it violates the UN Security Council resolutions and also the 1997 Chemical Weapons Convention.
The OPCW has also confirmed in its report of last week there are evidences that links chemical weapons being obtained by the IS terror group in Syria as well as Iraq.
If believed to the Kurdish authorities, the IS fighters had earlier this month fired mortar rounds equipped with mustard agent in northern Iraq.
Meanwhile, OPCW has sent its experts in Iraq to collect evidences related to the use of mustard gas by the IS group.
The White House showed its concern on Friday about the initial findings of OPCW.
Sulphur mustard is said to cause severe delayed burns to skin, lungs and eyes.
