More than a dozens deaths are believed to have been reported in Raqqa, Syria, as the epidemic – also known as H1N1 – sweeps through the region.
Extremists have been given guidance in Islamic State’s Al-Naba’a magazine on how to stop the virus spreading.
Fighters are told how to wash their hands properly and what to do if they suspect they have contracted Swine Flu.
The guidance is also believed to have been distributed in pamphlets in the Raqqa area.
According to watchdog Raqqa Is Being Slaughtered Silently (RIBSS), the epidemic had triggered “panic among civilians” and taken the lives of at least two children so far.
Meanwhile, three elite British troops were hurt under fire from Islamic State thugs during a top-secret mission in Iraq.
But the heroes’ bravery has not been officially acknowledged as Tory ministers lean on defence chiefs not to acknowledge the secret ground war being fought by our special forces in Iraq and Syria .
