Immediate Actions (RUN, HIDE, TELL)

If someone witnesses a terror attack, UK counter-terrorism guidance (from National Counter Terrorism Security Office – NaCTSO and Action Counters Terrorism – ACT) sets out very clear steps:

• RUN – If there’s a safe route, leave the area immediately.

  • Encourage others to come with you, but do not delay if they refuse.

  • Leave belongings behind.

• HIDE – If escape isn’t possible:

  • Find cover from gunfire or blast (brick walls, reinforced doors, large objects).

  • Stay away from windows.

  • Lock or barricade yourself in if possible.

  • Remain silent and turn phones to silent (including vibrate).

• TELL – Once safe, contact police by dialling 999.

  • Give clear details: location, description of attackers, weapons seen, direction of travel, any casualties.
