In the event of a terrorist incident, you should apply the advisory of “Run, Hide, Report” to stay safe:
RUN - To run out of the attacker’s line of sight and leave the scene via a safe route. More importantly, refrain from staying at the scene for taking photos or videos but leave immediately to avoid danger.
HIDE - If it is impossible to leave the attack scene, hide and lock yourself in a room, and then mute the mobile phone and turn off the vibration function as soon as possible. Refrain from using any items that can emit light or sound to avoid drawing the attacker’s attention.
REPORT - Call the police for assistance via 999 when safe or far away from the attack location.
