The World Health Organisation is investigating reports that ISIS militants have been showing up at an Iraqi hospital with Ebola.

According to three media outlets an undisclosed number of militants displaying signs of the disease attended a hospital in the ISIS-held city of Mosul, 250 miles north of Baghdad.

While the reports, from Kurdish and pro-Iraqi sources, remain unconfirmed, WHO spokesman Christy Feig said the group are trying to reach out to officials in ISIS-held areas to offer help.

UN workers are currently banned from entering ISIS-controlled areas in both Iraq and Syria so it is unlikely an operation in the region could be carried out.

Ms Feig told Mashable: 'We have no official notification from [the Iraqi government] that it is Ebola.'

The symptoms of ebola are similar to those of other diseases including malaria and yellow fever

Mosul has been under control of ISIS since June 2014 and over the past few weeks militants have reportedly executed more than a dozen doctors for refusing to treat injured fighters.

According to a report in Iraq's pro-government newspaper, al Sabaah, the disease was brought to Mosul by 'terrorists' arriving 'from several countries' and Africa.

The symptoms of Ebola, which include nausea and vomiting, diarrhea, bleeding and bruising, are similar to those of other diseases including malaria and yellow fever meaning it could easily have have been misdiagnosed.

In addition, very few ISIS fighters are believed to have travelled up from West Africa where the Ebola outbreak originated with most coming from areas where there have been no reports of the disease.

The reports have appeared in pro-government and Kurdish media but if true it could have catastrophic implications for people in ISIS-held areas as the group is against western science and medicine.

It is not known if any of the surviving doctors in Mosul are equipped to test for Ebola or trained to treat patients and prevent the spread of the disease.
