The group was uncovered after Labour sparked criticism by sending a 'dangerous' emergency warning over the country's extreme wildfire risk

Islamic State supporters in Britain have been handed a chilling guide on how to "overwhelm" emergency services with a blitz of wildfire arson.

An online forum has shared detailed instructions on deliberately starting wildfires and avoiding detection by police and forensic investigators.

One guide, first revealed by LBC, was titled "Burn down your first forest and exhaust the workers of the tyrant."

The detailed instructions offered advice on preparing for and deliberately starting wildfires.

The group was uncovered just weeks after Labour sparked criticism by sending a "dangerous" emergency warning about the country's extreme wildfire risk.

The notification, intended to reach all residents at 7pm with guidance against lighting fires in open spaces such as parks, moorland and woodland, continued sounding on numerous devices as late as 11pm, a full four hours after the initial broadcast.

It represented the most extensive deployment of the alert technology since its introduction in 2023, reaching millions of handsets nationwide.

Former police officer Norman Brennan told GB News that authorities must take action against the online forum.

He told the People's Channel: "We've seen how devastating wildfires are across Britain, and we've seen the devastation of wildfires across the whole of Europe that threaten towns, villages, and cities.

"Such forums are incitement for people to commit a criminal offence. The criminal offence will be setting wildfires up, and we all know that if you look at Europe and mainland Britain, it overwhelms the local fire services.

Often counties have to send backup and reinforcement units to assist their fellow neighbours, and if people take this incitement to light fires seriously, which there's no reason to suggest they won't, it absolutely will overwhelm the services."

The former officer said authorities and MI5 must take this seriously because it is a form of terrorism.

He added: "Anti-terrorist squads need to clamp down and monitor these, and where appropriate, pre-arrest anyone that looks as though they're going to get involved, and anyone that does should be arrested immediately, and there should be no bail clauses."

Mr Brennan suggested that emergency legislation should be passed to introduce sentencing powers, meaning bail would be refused and suspects would be remanded in custody.

He said: "This absolutely must be taken seriously, and the strongest of pre-warning threats by the government and the criminal justice system to warn that there will be severe consequences. It mustn't just be soft words or toothless threats."

Islamic State propaganda was similarly used to exploit the devastating Los Angeles fires in 2025.

The terrorist group urged supporters to start further fires while unofficial propaganda outlets amplified the message.

Isis remains a significant and active threat to Britain, with security agencies warning that the group has actively resumed its efforts to export terrorism to the UK and its allies.

The UK's national terrorism threat level currently sits at "Severe", meaning an attack is "highly likely".

After the emergency alert was sent, Reform UK Wales branded the approach "dangerous", while Alex Burghart, the Conservative Shadow Northern Ireland Secretary, condemned the use of the system as disproportionate, warning it set a troubling precedent.

He said: "When the severe alert system was established, it was made clear that there will be a very high threshold for its use based on strict criteria centred on an immediate risk to life. The use at a national level clearly doesn't hit that threshold and opens the door to future misuse of the system."

Shadow Housing Secretary Sir James Cleverly accused Labour of being "drunk on power", telling GB News the system was meant for "very, very rare, serious, life-threatening and immediate emergencies".

He said: "This is another example of a Labour Government drunk on power, abusing its position, abusing the mechanisms of the state to try and get ahead of the news cycle."

Responding to the investigation, a Home Office spokesman said: "We take all threats posed to British interests and lives seriously. Our police and security services are backed by some of the strongest counter terrorism powers in the world, and they work tirelessly to defend the UK against the range of hostile threats we face."

In a press release published shortly before the alert, Louise Haigh, who heads the Cabinet Office as Chancellor of the Duchy of Lancaster and gave the green light for the nationwide alert, said: "In response to the continued risk posed by wildfires, the Government has taken the decision to issue an Emergency Alert to England and Wales.

"This is the most extensive use of the UK’s Emergency Alert system in response to an active incident, and reflects the seriousness with which the Government is acting to safeguard people and property."

GB News has reached out to the Home Office for further comment.
