Alalam - Europe
The terrorists' ambition is to slaughter as many people as possible using "whatever means possible" and they would have no "moral objection" using the weaponry, the security expert explained.
Security minister Ben Wallace said there was an "aspiration" among the terror nuts to carry out these types of atrocities in Europe including Britain.
He told The Sunday Times: “They have no moral objection to using chemical weapons against populations and if they could, they would in this country.
“The casualty figures which could be involved would be everybody’s worst fear."
Britain must brace itself for any potential inside enemies, he added.
Mr Wallace warned the threat is "real" as there are people trying to carry out terrorist attacks.
He added: “There are traitors.
We have to be on our guard for the enemy within.
“The insider threat, as we would call it, is real and it can be exploited and there are people trying to do that as we speak.”
