The so-called Islamic State (IS) group would be prepared to carry out a chemical weapons attack on the United Kingdom, security minister Ben Wallace has said.
He said: "The ambition of IS (ISIS) or Daesh is definitely mass-casualty attacks. They want to harm as many people as possible and terrorise as many people as possible".
According to the minister, any specific chemical attacks plot has been identified but the terrorists have "no moral objection to using chemical weapons against populations, and if they could, they would in this country".
"The casualty figures that could be involved would be everybody's worst fear", he noted, citing the dismantlement of an Islamic State cell in Morocco in February as evidence that the terrorists plan to carry out chemical attacks in Europe.
The Islamic State terror group is plotting mass casualty chemical attacks against Britain, a senior United Kingdom minister has warned. He also expressed his fear that IS's territorial losses in Iraq and Syria may encourage its members to commit further atrocities in Europe.
Mr. Wallace added that since the terrorist group had faced defeating battles and had been forced to leave their stronghold in places such as Mosul, Iraq, along with other major locations in the Middle East, then the British fighters in ISIS would probably return to the United Kingdom in order to carry on with their attacks and threaten the rest of the citizens.
In an interview with the Sunday Times, security minister Ben Wallace said the terrorist group has used chemical weapons in Syria and Iraq, where it controls large areas, and that intelligence chiefs believe it has an "aspiration" to use them in Britain.
About 800 Britons went to fight in Syria and just under half have returned.
"Moroccan authorities dismantled a cell involving chemical weapons".
The OPCW experts analyzed samples of mustard gas employed in the August 2015 attack and found that there's grounds to believe "this substance may have been produced by ISIS itself", Uzumcu told AFP. Around 100 have been killed. Wallace said the figure for 2016 would be "very similar". We know there are a significant number of [Britons] fighting for IS in Syria.
He said numerous threats came from ungoverned spaces in the Middle East - namely Iraq and Syria.
In March, three coordinated suicide bombers attacked the airport and metro system in Brussels, with Isis claiming responsibility.
