Foreign travel advice
There is a high threat from terrorism. Attacks could be indiscriminate, including on public transport and transport hubs and in other places visited by foreigners.
Brussels hosts a number of international institutions (EU and NATO) and government and foreign embassy buildings which are sensitive locations.
There is considered to be a heightened threat of terrorist attack globally against UK interests and British nationals, from groups or individuals motivated by the conflict in Iraq and Syria. You should be vigilant at this time.
