The four-minute film, which was created by Counter Terrorism police alongside the Foreign Office and ABTA The Travel Association, was launched to the public on Monday 10 July and has since been viewed more than a million times on YouTube, Facebook and Twitter.
The chances of being involved in a terror attack are very small, but holidaymakers travelling abroad this summer have flocked to watch this video so they are prepared to act should the worst happen.
As UK schools break up for summer holidays and the travel industry enters one of the busiest periods of the year, police are once again asking the public to keep themselves safe abroad by watching the film before they travel.
Detective chief superintendent Scott Wilson, National Coordinator for Protect and Prepare, says: I am delighted that the public have received this advice so well and that so many people have taken the time to prepare themselves in the incredibly unlikely event of being caught up in an attack.
One million views means that there are potentially one million more people in the UK who are better prepared to act.
This video is not intended to scare people, simply to make them spend a few minutes thinking about what they would do if the worst should happen.
We want people to think of this in the same way they do the safety film airlines show before take-off. They dont expect anything bad to happen but it is a sensible safety precaution to show people what to do.
