This is the tragic scene as a young girl being cradled in her father's arms is awaiting a flight to Turkey for treatment after being injured in a sickening mustard gas attack in Iraq by ISIS.

The terrorists launched multiple rockets containing the deadly toxin on the town of Taza which killed a three-year-old girl.

Scores of innocent civilians were injured during the attack after they came into contact with the deadly and corrosive substance.

This young girl is one of 1,500 people injured in an ISIS mustard gas attack on the village of Taza in northern Iraq last month. A group of those wounded in the strike are flying to Ankara, Turkey for specialist treatment

More than 25,000 people have fled the town of Taza since ISIS launched their mustard gas attack

As well as scalding, mustard gas can cause respiratory problems and in the most severe cases, death

Intelligence sources believe that ISIS has been developing its own chemical weapons which it has already used against civilian targets.

Three people died in the immediate aftermath of the attack on March 9, including a six-month-old baby.

ISIS fired the rockets into the town of Taza, south of Kirkuk.

Local officials said 1,500 people were affected by the gas, suffering burns, rashes and respiratory problems.

Some of the victims are being flown to Ankara, Turkey for specialist medical treatment.

The exact chemical agent used in the attack has not been identified, although it is thought to be mustard gas.

ISIS launched the chemical warfare attack on Taza from their stronghold of Bashir which is five miles south

Victims of mustard gas attacks often take several weeks to die as blood slowly pools in their lungs

The terrible gas does not need to be inhaled to cause damage, if it makes contact with the victim's skin it can continue to irritate the area for several weeks after exposure

Samples of the substance have been collected and sent to the Organisation for the Prohibition of Chemical Weapons in The Hague.

Despite the small number of people killed in the attack, the use of chemical weapons has a huge psychological impact on the civilian population.

In the past week, more than 25,000 people have fled the town, which is about 135 miles north of Baghdad.

The chemical attack was launched from the neigbouring town of Bashir which is under ISIS control.

Iraqi prime minister Haider al-Abadi said his government had launched a number airstrikes on ISIS positions following the attack.

In February, US Director of National Intelligence James Clapper and CIA Director John Brennan for the first time openly accused IS of using chemical weapons, including mustard gas, in Iraq and Syria.

As well as mustard gas, ISIS is believed to have attempted to modify mortar rounds to carry chlorine gas.

Victims of the attack might not show symptoms for several days after exposure to mustard gas

Exposure to mustard gas can cause severe blistering and cause permanent and painful damage

ISIS is believed to have developed the capacity to manufacture its own stockpile of chemical weapons
