Safety and Security:
Denmark remains largely free of terrorist incidents; however, like other Western European nations, Denmark faces an increased threat of terrorism. In 2011 and 2012, police arrested individuals accused of planning terrorist attacks in Denmark. In particular, the 2005 and 2010 publication in Denmark of cartoons depicting the Islamic Prophet Muhammad continues to impact Danish relations with the Muslim world and draw the attention of extremists. The Department of State recently re-issued the Worldwide Caution, which includes information about the potential for terrorist attacks in Europe.
As with other countries in the Schengen area, Denmark’s open borders allow for the possibility of terrorist groups entering and exiting the country with anonymity. You are reminded to remain vigilant with regard to your personal security and to exercise caution. In general, Copenhagen is a safe city. However, certain areas pose more of a threat than others; for instance, you should avoid downtown Vesterbro and Nørrebro late at night.
Public demonstrations occasionally occur in Copenhagen and other cities, and are generally peaceful events. Prior police approval is required for public demonstrations, and police oversight is routinely provided to ensure adequate security for participants and passers-by. Nonetheless, as with any large crowd composed of diverse groups, situations may develop which could pose a threat to public safety. You should avoid areas where public demonstrations are taking place. Be aware that participation in illegal demonstrations or street riots may result in immediate imprisonment and long-term bans on re-entering Denmark.
