- Islamic State has executed four woman by rape and stoning.

- The four were sentenced to this horrible fate for adultery by an ad-hoc sharia court.

- The terror group has also recently been discovered using chemical weapons against its enemies.

Members of the so-called Islamic State have raped and stoned four women to death after accusing them of adultery.

The jihadis arrested the victims after they claimed to have caught them in the act.

At an IS-led sharia court they were sentenced to death by stoning, without the court mentioning any details of the men they had reportedly had sex with.

Media activist Abdullah al-Malla said: “The four women were most likely exposed to sexual abuse at the hands of IS militants before being driven out of their homes and transferred to the Sharia Court.

“Apparently, the victims have been raped by IS jihadis and then stoned to death on charges of committing adultery.”

This latest news about Isis comes after the terror group was accused of using chemical weapons in its war with Kurdish freedom fighters.

The Organisation for the Prohibition of Chemical Weapons (OPCW) confirmed that laboratory tests had come back positive for the sulphur mustard, after around 35 Kurdish troops were sickened on the battlefield last August.

The samples were taken after the soldiers became ill during fighting against Islamic State militants southwest of Erbil, capital of Iraq's autonomous Kurdish region.

The OPCW already concluded in October that mustard gas was used last year in neighbouring Syria.

Sulphur mustard is a Class 1 chemical agent, which means it has very few uses outside chemical warfare.

Used with lethal effectiveness in World War One, it causes severe delayed burns to the eyes, skin and respiratory tract.

Experts believe that the sulphur mustard either originated from an undeclared Syrian chemical stockpile, or that militants have gained the basic know how to develop and conduct a crude chemical attack with rockets or mortars.
