Two people have been hospitalised after a “significant fire” broke out at the BAE Systems nuclear submarine shipyard in Barrow-in-Furness, police have said.
Emergency services were called to the site, where the UK’s nuclear submarines are built, at about 00:44 GMT on Wednesday.
Those taken to hospital were said to be suffering from suspected smoke inhalation and have since been released, BAE confirmed, with everyone “accounted for”.
Cumbria Police said there was “no nuclear risk”.
