Germans' fears about their nation being a terrorist target have jumped sharply in the wake of this week's knife-and-axe attack on rail passengers in the southern state of Bavaria, according to a poll published on Friday.
The poll released by state broadcaster ZDF found that 77 per cent of Germans believe that their country will face terrorist attacks in the near future. Two weeks ago, the figure stood at 69 per cent.
Only 20 per cent of Germans believe that the country is not threatened by terrorist attacks in the near future - down from 28 per cent two weeks earlier.
Mannheim-based pollster Forschungsgruppe Wahlen conducted the survey for ZDF after four people were seriously injured in Monday's train attack by a 17-year-old refugee, who Berlin officials believe was from Afghanistan and who had been spurred to act by Islamic State propaganda.
He was shot dead by police after also attacking a passer-by.
The assault on the train near the city of Wuerzburg came just days after a lorry attack on a crowd celebrating France's national day in the southern French city of Nice in which 84 people died.
German officials say security forces have so far managed to foil several possible terrorist attacks on the nation.
The ZDF poll also found that 59 per cent of Germans are confident that the security services are doing all they can to protect the nation from attacks.
