Passengers using Bristol Airport have been warned of delays following an early morning evacuation after a smoke alarm was set off.
Images on social media showed a crowd stood outside in freezing conditions after the alarm went off at around 6.15am.
The airport tweeted that the departure lounge was evacuated but that all passengers had returned to the terminal.
However, there are likely to be some delays to flights and some will need to be rechecked at security.
More than 480,000 passengers used Bristol Airport in January on nearly 5,000 flights.
