It is only natural to panic if you are caught in a life-threatening situation.
However, there is a 3-step process that anyone can adopt in case of a terror attack.
While no one hopes to be caught in such a situation, it always pays to be prepared.
The steps are shown in a 4-minute video, released by the UK counter-terrorism police, advising holidaymakers on how to respond if the threat is imminent.
The video was made in association with the Foreign Office and the travel association ABTA, in anticipation of vacationers jetting off to sunny destinations in the upcoming months.
Footage shows holidaymakers relaxing at a hotel before the building comes under fire, reminiscent of the June 2015 attack in Tunisia, during which 30 British people were killed at a hotel in Sousse.
The short film is centered around the safety message of 'Run, Hide, Tell.'
Holidaymakers are advised to run if there is a safe route, hide if running is not possible, and to tell the police of the attack once it is safe to do so.
UK police first launched the ‘Run, Hide, Tell’ advice in December 2015 after attacks in Paris. It was recently re-issued to the public by officers during London’s Borough Market incident.
According to a report from The Independent, the national coordinator for the Government's Protect and Prepare initiative, detective chief superintendent Scott Wilson, said: "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."
Some other tips include leaving belongings behind when fleeing, encouraging others to come with you, turning your mobile phone to silent when in hiding, and moving away from the door after locking it.
There's even advice for responding to police arrival, such as not making any sudden movements to avoid being seen as a threat during situations where it may be difficult for armed forces to differentiate attackers from civilians.
In further preparation, more than 20,000 travel representatives have been trained in safety measures including how to spot suspicious items and activity, as well as what to do in the event of a major terrorist incident, the Mirror reported.
