Brussels, Rabi' II 1, 1438, December 30, 2016, SPA -- European capitals tightened security today ahead of New Year's celebrations, erecting concrete barriers in city centres and stepping up police numbers after the "Daesh" terrorist organization attack in Berlin last week that killed 12 people. In the German capital, police closed the Pariser Platz square in front of the Brandenburg Gate and prepared to deploy 1,700 extra officers, many along a party strip where armoured cars will flank concrete barriers blocking off the area. In Milan, where police shot the man 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 tourists 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. -- SPA 19:57 LOCAL TIME 16:57 GMT www.spa.gov.sa/w301721
