European cities are keeping forces on high alert ahead of New Year’s Eve following a series of terror attacks in the continent, most recently on a Berlin Christmas market where 12 people were killed.

In Berlin, police closed the Pariser Platz square in front of the Brandenburg Gate and prepared to deploy 1,700 extra officers. “Every measure is being taken to prevent a possible attack,” Berlin police spokesman Thomas Neuendorf told Reuters.

In Milan, where police shot the terrorist dead, security checks were set up around the main square. Trucks were banned from the centres of Rome and Naples. Police and soldiers cradled machine guns outside tourist sites including Rome’s Colosseum.

Madrid plans to deploy an extra 1,600 police on the New Year weekend. For the second year running, access to the city’s central Puerta del Sol square where revellers traditionally gather to bring in the New Year will be restricted to 25,000 people, with police setting up barricades to control access.
