Following the evacuation of Charlie Stayt and Naga Munchetty from the BBC Breakfast studio, fans were alarmed.
On Friday morning, the pair was reporting live when the show was abruptly yanked from the air.
A news coverage was switched to BBC News, leaving viewers apprehensive, as Naga and Charlie were hurried out of the premises, with a live report from Aerospace Bristol abruptly turning to a presenter covering the Israel-Hamas war.
‘Hope everyone in #BBCBreakfast studio is ok and it’s just a technical glitch,’ one person wrote.
Another commented: ‘It’s weirdly unnerving.’
Someone else said: ‘Building was evacuated – #bbcbreakfast is back. Phew!’
‘I hope everyone is OK on @BBCBreakfast Odd switch to @BBCNews,’ a fourth penned.
Returning to the red sofa after several minutes, Naga explained: ‘You’re returning to BBC Breakfast.
‘Apologies, we had an evacuation in the building but we are back now with you to keep you up to date with the latest in the news.’
It is unclear whether the evacuation was due to a fire alarm or another issue.
This isn’t the first time a BBC fire alarm has disrupted live television.
Presenters Rachel Burden and Roger Johnson were midway through an interview with The Apprentice winner Harpreet Kaur in March of last year when they were stopped.
‘We’ve been disturbed by an alarm which may mean that we have to slow things down for a moment,’ Rachel said, after an alarm went off.
‘I’m so sorry everyone. For the time being, we’re going to have to leave the studios.
‘So we’ll see if we can come back before the end of the show,’ she explained.
Over the alarm, a voice could be heard saying: ‘Attention, attention, please evacuate the building via the nearest exit. Please do not use the lifts.’
