       The FCDO says Greece is also at risk of a terrorist attack, noting there have been several, "involving explosives and automatic weapons against Greek institutions, shopping malls, banks, media offices, diplomatic premises and the police".

       Britons are warned that Greek authorities have heightened security at some prominent locations, including tourist sites, due to the Israel-Hamas war and the unrest it has provoked internationally.

       "There is currently a heightened risk of such protests, particularly in central Athens," officials said.

       People are urged to steer clear of protests and follow the advice of local authorities.

       Officials also flagged the following regular demonstrations that take place in central Athens.

       The FCDO also warned that "Demonstrations, political gatherings or marches can take place" in the country "with little or no warning, particularly in cities", and recommended visitors follow the advice of police and local authorities.

       "While most demonstrations are peaceful, there is a risk of unrest or violence," the warning adds. "If you’re near areas where demonstrations are taking place, be aware of what is happening around you and move away if there are signs of disorder."

       The department also warns visitors to be vigilant about street crime, as well as "highway pirates".

       "‘Highway pirates’ target foreign-registered and hire cars, especially those towing caravans. They may flag you down, claiming there is something wrong with your car or that you have damaged theirs," the department said.

       "If you decide to stop to check the condition of a vehicle, stop in a public area with lights, such as a service station. Be wary of anyone offering help."

       Among its other warnings are over thefts from parked cars, particularly in the Colosseum area of Rome, Ostia, Milan and Pisa.

       "Thieves also target coastal areas and towns, and motorway service stations," it warns. "Avoid leaving luggage in your vehicle – even out of sight in the boot – for any length of time.

       "Thieves may use a variety of methods to distract you or encourage you to stop your car, including asking for help or directions or pointing out a fictional fault with your car," the warning adds.
