Senior staff from across Gibraltar have been planning and rehearsing the action to be taken in the event of a terrorist incident on the Rock.

Entirely based in the Civil Contingencies suite in No6 Convent Place, Exercise Assure involved officials from Government, RGP, MOD, the Port, the Air Terminal, BCA, HM Customs and other specialist staff.

His Excellency the Governor, the Chief Minister, the Commissioner of Police and CBF were also involved in the decision-making process.

The exercise scenario was based on a truck causing multiple casualties, followed by a manhunt in the Upper Town.

Later this year it is hoped to run a similar, realistic exercise in a small area of town and possibly involving members of the public.
