The Metropolitan police have shared valuable advice on what to do in the event of a terrorist attack.
In the UK, the threat level is currently set at severe, which means an attack is highly likely.
With recent tragic events in Europe, including the Berlin bus attack in 2016, which killed 12 people and the November 2015 Paris attacks, which killed 130 people, the police are warning people to be prepared.
Assistant commissioner, Mark Rowleyc from Counter Terrorism Policing, said: "Everyone's aware of the terrorist challenges across the world and there've been some awful attacks.
"It's our view that this advice should be rolled out to the public so in the tragic event that anyone gets caught up in a marauding firearms or weapons attack, they're better informed and better advised to protect themselves."
The Met police's Counter Terrorism Policing tweeted the video on January 4 to remind people of what they should do in an attack.
The Met police tweet reads: "Watch this short video explaining what you should do in the unlikely event of a terrorist attack - it could save your life #RunHideTell."
The video stresses three things to remember, to run, hide and then tell:
- Check for a safe route.
- Insist others go with you.
- Don't let them slow you down.
- Leave your belongings behind.
- Hide if you can't run.
- Find cover from gunfire.
- Lock the door and create a barricade.
- Move away from the door.
- Be quiet and remember to put your phone on silent.
- When safe, dial 999.
- Give your location.
- Tell police the direction the attacker is moving in.
- If safe to do so, stop others from entering the area.
Once the police arrive do as they tell you and ensure you follow the following instructions:
- Don't make any sudden movements or gestures.
- Stay calm, don't wave your arms or shout.
Keep your hands visible.
Senior national coordinator for counter terrorism policing, Neil Basu, said: "The chances of ever being caught up in an attack are very small, but it if did happen you would not be thinking straight.
"You need a simple message that will quickly come to you - Run, Hide, Tell.
"We know from our research that a lot of people are familiar with the message but we want everyone to watch the video and be aware of what to do."
