There is a high threat from terrorism. Attacks could be indiscriminate, including on public transport and transport hubs and in places frequented by foreigners.

The Belgian authorities have changed their threat level for the Brussels Region to level 3 ie a possible and real threat.  The same threat level now applies to all of Belgium.

The Belgian government announced on 26 November that the Brussels Region threat level is at Level 3 – a possible and real threat. Level 3 now applies for the whole of Belgium. You should remain alert and vigilant, and follow the instructions of the Belgian security authorities. You can find more information on the Belgian Crisis Centre website and Twitter feed.

Over-ground trains, (including international services), airports, trams and buses are operating. The Brussels metro network is expected to resume normal service from 27 November with additional security in place.

There have been a number of police raids in the Brussels Region and other Belgian cities in the past week. Belgian security operations are likely to be carried out at short notice. If you’re in an affected area you should follow the instructions of the Belgian security authorities. Police have asked the public not to comment on police operations on social media.

The Belgian authorities and International Tennis Federation (ITF) have put in place increased security measures at the Davis Cup Final, including additional checks at all entrances to the venue. These will apply to all ticket holders, staff members and visitors, so allow time in your travel plans for any delay this may cause. The ITF has advised that entry into the event will take longer than usual. Bags and backpacks won’t be permitted into the venue. Storage facilities will be available off-site. For further information please check the Tennis Flanders website.

Some public events may be cancelled and some tourist attractions closed. Contact event organisers for information on whether specific events are going ahead.

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.
