The French government has announced a period of national mourning up to and including Monday 18 July for the victims of the recent attack in Nice.
At least 84 people died when a lorry driver deliberately rammed Bastille Day crowds on the promenade des Anglais.
In the UK you may fly the national flag at half-mast whenever you feel it is appropriate.
You may also fly the French national flag at half-mast.
If you do so alongside a UK national flag, however, the latter must also be at half-mast or removed.
You should remove any other national flags, and all other flags in the same set must be at half-mast.
Special provisions apply where a flag cannot fly at half-mast; for example, if it is on an angled pole projecting from a building.
Here you may add a black cravat or ribbon to the top of the flag, closest to the flag pole.
For full guidance on flying flags at half-mast, see Flying Flags in the United Kingdom, free to download here.
Our thoughts and prayers are with the people of Nice and the families and friends of those killed and injured in this horrible attack.
