Islamic State, also known as Daesh, still poses a threat to the UK, Air Commodore Roddy Dennis told Forces News.
He warned that ISIS has not been beaten yet and operations will continue “for some time” against the extremist group.
Iraq’s Prime Minister announced in December that the war against Islamic State was over and that Iraqi troops were now in complete control of the Iraqi-Syrian border, which contained the last few areas IS held.
Air Commodore Dennis said: “We are operating in Iraq and we’re there on the invitation of the government of Iraq so, of course, we want to see that progress.
“But I think he was quite clear with his announcement that there was the liberation of Iraq but Daesh aren’t defeated yet.”
The RAF officer added that ISIS are still a threat to the UK.
He said: “They still present a threat to the UK so operations are continuing and I think they will for some time.”
The terror group was defeated in Iraq and removed from their headquarters in Syria last year.
The jihadist group had seized large swathes of Syria and Iraq in 2014 when it proclaimed a “caliphate” and imposed its rule over some 10 million people.
The UK has launched airstrikes and trained Iraqi forces in the battle against ISIS since Britain got involved in the fight in 2014.
Air Commodore Dennis added that British forces are “absolutely focused” on defeating the extremist group.
He said: “We’re absolutely focused, as this awful terrorist organisation that they are, to do whatever we can as part of a whole government effort to defeat Daesh and really remove that threat from the UK.”
