“Terrorist attacks in Serbia cannot be ruled out. Attacks could be indiscriminate, including in places visited by foreigners.

“Terrorists may target religious sites, including churches. There may be increased security in place during festive periods and other major events that might attract large crowds. Remain vigilant and follow the advice of the local authorities.

“In June 2024, a lone attacker fired at a police officer with a crossbow outside the Israeli Embassy in the Savski Venac area of Belgrade.”

This comes as the Government shared that another popular European destination “cannot rule out” terrorist attacks.

Guidance from UK Counter Terrorism Policing reads: “The chances of being caught up in a terrorist incident are low but sadly we have seen atrocities take place in the UK and abroad. It is important everyone stays alert and knows what to do if the worst was to happen.”

Britons were told to complete three tasks before heading on their travels. Holidaymakers should check the latest UK Foreign and Commonwealth Office Travel Advice for the country they are visiting.

They should also ensure they have adequate travel insurance – taking time to check the small print. Lastly, holidaymakers should watch UK Counter Terrorism Policing’s holiday safety film.

Britons were advised to run, hide and tell. Experts advised: “If you find yourself in an emergency, run to a place of safety. This is better than trying to surrender or negotiate.

“It is better to hide than confront. Barricade yourself in, turn your phone to silent and use only when it is safe to do so.

“Make sure you know the local emergency numbers in the country you are travelling to. For all EU countries, call 112.”

Holidaymakers were also advised to consult the FCDO’s guidance on how to reduce their risk from terrorism while abroad.

Britons were told: “International terrorism remains a serious threat to British nationals living or travelling abroad. Although global counter-terrorism efforts against groups including Daesh (otherwise known as Isil or Isis) and Al-Qaida have reduced the threat in some locations, Islamist terrorism remains an ongoing threat.

“Terrorists are also increasingly motivated by a range of ideologies, including the extreme right wing. The terrorist threat is rising across the world due to increasing global instability.

“Foreign, Commonwealth & Development Office (FCDO) Travel Advice aims to provide information and advice about foreign travel, including terrorism and other risks you may face abroad. This is so that you can make better-informed decisions about your own travel.

“The FCDO constantly reviews the threat to British nationals from international terrorism using all of the resources and information available, including information gathered by the intelligence services. There may sometimes be constraints on how far public information can reflect intelligence information.”
