Safety and Security:
Belgium has been largely free of major terrorist incidents. As with other countries in the Schengen area, Belgium maintains open borders with its neighbors, allowing the possibility of terrorist operatives entering/exiting the country with anonymity. Belgian law enforcement and security officials, in close cooperation with neighboring countries, maintain an effective anti-terrorism effort and a welcoming environment for tourism and business.
Prior police approval is required for all public demonstrations in Belgium, and police are present to ensure adequate security for participants and passers-by. Nonetheless, spontaneous demonstrations do take place in Belgium from time to time in response to world events or local developments. Even demonstrations that are meant to be peaceful can become violent and unpredictable. You should avoid them if at all possible. Be alert and aware of your surroundings, and pay attention to what the local news media have to say.
