British holidaymakers warned to be on alert for terror attacks abroad this summer
Anti-terror cops are urging Britons travelling abroad this summer to be alert to the threat of terror attacks
The safety video urges anyone caught up in a terror attack to 'run, hide, and tell'.
Three years ago 30 British holidaymakers were killed in a massacre carried out by a gunman on a beach in the Tunisian resort of Sousse.
Chief Superintendent Nick Aldworth, of the Metropolitan Police, said: "We want people to think of this in the same way they do the safety film airlines show before take-off.
He added that the chances of being caught up in a terror attack abroad are 'low'.
