Security beefed up amid terror worries

Police, military forces in many cities around the world placed on alert

Europe ushered in the New Year with heightened security fears on Friday as German police evacuated two train stations in Munich, citing a tip about a planned suicide bomb attack, and Belgium held three people over an alleged plot.

Security forces in many capitals were on raised alert after a year of militant attacks, including an attack in Paris in November that killed 130 and was claimed by Islamic State.
