Five people have been arrested in England and Wales on suspicion of involvement in right-wing terrorism.
The detained individuals include a 16-year old boy who was arrested in Swindon on suspicion of involvement in the commission, preparation or instigation of acts of terrorism.
The other suspects include a 28-year-old woman and two men, aged 29 and 30 from Keighley (West Yorkshire) and a 28-year-old man from Anglesey (Wales).
According to multiple reports, all five suspects have been transferred for questioning to an unnamed police station in West Yorkshire.
According to Counter Terrorism Policing North East (CTPNE), the arrests form part of an “ongoing investigation” into right-wing terrorism.
Meanwhile, West Yorkshire Police has hinted that explosives may have been found at an address in Keighley.
In a statement the force said: "Following the discovery of potentially suspicious material at one of the addresses in Keighley the Explosive Ordnance Disposal Unit has been called to provide specialist advice and to arrange the safe removal of the items if required”.
The latest raid against far right extremists suspected of plotting a terrorist attack comes against the backdrop of heightened concern in the UK about the dramatic rise in extremist right wing activities.
Only last month the Home Secretary, Priti Patel, started the process of proscribing an American neo-Nazi group with deep ties to British extremist circles.
The Atomwaffen Division (AWD), which is linked to five murders in the US, reportedly wields strong influence within the far-right community in the UK.
