They are the terrible scenes that the world had hoped it would never see again after the horrors of the First World War.
But now The Mail on Sunday has uncovered the first shocking evidence that Islamic State is using mustard gas on the front line in Iraq.
Troops fighting against the terror group have been left with appalling injuries – including agonising blisters on their skin and badly damaged lungs – in a frightening echo of warfare in the trenches on the Western Front.
Without any regard for the international ban on the chemical weapon, IS has used the lethal gas repeatedly against Kurdish forces who are battling to drive out the jihadis.
The terror group – which has killed hundreds of victims in repeated attacks in France and against other targets in the West – is fighting a last-ditch battle to hold on to the dwindling area it controls in Iraq and Syria.
Nearly 100 Kurdish soldiers have been injured in mustard gas attacks, which are now taking place as often as twice a week, according to doctors speaking publicly for the first time.
The Mail on Sunday has interviewed victims of the weapons, which are banned by the United Nations.
They described poisonous yellow clouds of mustard gas burning their skin and damaging their lungs.
