The terrorist incidents, which took place on Friday November 13, claimed at least 129 lives and resulted in widespread casualties.
As a mark of respect and expression of solidarity, all Whitehall government departments have lowered their Union Flags to half-mast.
Local authorities are not bound by the request, but may wish to follow it for guidance. Devolved administrations are responsible for issuing instructions for the flying of the Union Flag on buildings in their estate and others as necessary.
Members of the public who have been directly affected by the incidents in Paris, or who are concerned about family members and friends who may be directly affected can call the Foreign and Commonwealth Office on 020 7008 0000.
