Belgium, like many European countries, has a risk of terrorism. The main threat is from Extremists aligned or in support of Daesh. In recent years there have been several high-profile terrorist attacks in the region, including both opportunistic and coordinated attacks. On 22 March 2016, a significant attack was orchestrated and executed at Brussels Zaventem airport and the metro system, causing mass fatalities and destruction.
Terrorism remains a security concern for the population, and terrorist groups are likely to have the intent and capability to carry out further attacks in the future. Areas most vulnerable could include government buildings, transportation networks and infrastructure, or high-profile commercial interests.
Opportunistic crime poses a credible threat to foreign visitors, and densely populated areas are most vulnerable, especially the known tourist hotspots. Criminals will target individuals who are unaware of their surroundings and have their valuables on display.
