Counter terrorism police are urging all holidaymakers to watch their 'Run, Hide, Tell' video - so they know what to do if they are caught up in a terrorist attack while abroad this summer.
The UK's most senior counter-terrorism police say the video has been watched seven million times since it was first released in 2017.
And they are promoting it again this holiday season.
Chief Superintendent Mick Orchard, National Coordinator for Protect and Prepare, says it's important to know how to react should the worst happen.
He said: "The chances of being caught up in a terrorist incident are still low, but sadly we have seen atrocities take place in the UK and abroad.
"So it is important everyone stays alert and knows what to do if the worst was to happen.
"An important part of my job is deploying police officers and staff around the world to share the UK’s world renowned security expertise, to better protect our citizens from harm.
"Now we are asking the public to play an active part, by taking the time to watch this video.
"We want people to think of this in the same way they do the safety film airlines show before take-off.
"They don’t expect anything bad to happen but it is a sensible safety precaution to show people what to do."
